-% \section{Introduction}
-% A \emph{Template} is a named `function' that has a fixed number
-% of \emph{mandatory arguments} and an additional set of \emph{keys}
-% or `named attributes' that are set in a `key value list'. That is,
-% a comma separated set of assignments of the form:\\
-% \meta{key$_1$} |=| \meta{value$_1$} |,|
-% \meta{key$_2$} |=| \meta{value$_2$} \ldots
-%
-% More specific instances of the template may be declared by
-% specifying settings of the parameters. The key value list is parsed
-% at the time the instance is declared, and an `internal' set of
-% parameter assignments is passed to the template code. It is normally
-% not parsed at run-time, though it is possible to enforce this
-% behaviour.
-%
-% Templates have a \emph{type} and a \emph{name}. Templates
-% of the same type have the same argument and parameter
-% structure. That is, templates of the same type are expected to be
-% exchangeable semantically. (However, except for checking that
-% templates of the same type always have the same number of arguments
-% this is not enforced by the code.)
-%
-% A template type is declared via the |\DeclareTemplateType|
-% declaration which takes two arguments: the name for the type and the
-% number of arguments a template of this type requires.
-%
-% Templates are declared via the |\DeclareTemplate|
-% command which takes five arguments
-% \begin{itemize}
-% \item The \emph{type} of the template (no |\|).
-% \item The \emph{name} of the template (no |\|).
-% \item The number of arguments for the template (same as on type
-% declaration).
-% \item A list declaring the keys accepted by the template,
-% with information about the action to take when the key is specified
-% with a value.
-% \item The code for the template. This may be arbitrary \TeX\
-% code. At some point it should execute |\DoParameterAssignments|
-% to run the parameter assigments.
-%
-% The mandatory arguments are accessed via |#1|, |#2|, \ldots
-% \end{itemize}
-%
-%
-% Each element of the key specification list is of the form:
-% \begin{flushleft}
-% \meta{key name} |=|
-% \meta{key type} \meta{optional default} \meta{internal code}
-% \end{flushleft}
-%
-% The \meta{key types} are essentially specified by giving a symbolic
-% representation of the assignment function to be used by \TeX.
-%
-% Currently the possibilities are
-%
-% \begin{center}\catcode`|=12
-% \begin{tabular}{l|ll|l}
-% key type& letter& internal code& argument form\\\hline
-% Command & f\emph{n}&command name & command definition\\
-% name & n & command name & command definition\\
-% length & l & length register& calc length syntax\\
-% fake length & L & command name & calc length syntax\\
-% count & c & count register& calc count syntax\\
-% fake count & C & command name & calc count syntax\\
-% boolean & b & name of \verb|\newif| switch& true or false\\
-% switch & s & \marg{true code}\marg{false code}& true or false\\
-% instance& i\marg{type}& command name& instance of this \emph{type}\\
-% direct & x & Internal code& any\\
-% general & g & general code & any
-% \end{tabular}
-% \end{center}
-%
-% In addition, any of these types may be prefixed by |+| to
-% denote a global assignment (described below).
-% |f| takes a digit from 0--9 to denote the number of arguments.
-% |n| is in fact the same as |f0|. When an instance is declared
-% The value assigned to the key should be the definition of
-% the command, using |#1|\ldots|#9| to denote the specified arguments.
-%
-% |c| takes an internal form a count register,
-% not a \LaTeX\ counter name.
-%
-% For |f|, |n|, |l|, and |c|, the assignment is done twice, once
-% at the time an instance is \emph{declared}. (This may involve
-% using \textsf{calc} expresions. Then the `primitive assignment'
-% of the value (not using calc) is copied to the internal parameter
-% list, to be executed when an instance is run. Sometimes you need the
-% expression to be evaluated at the time an instance is run rather
-% than the time it is declared. For example it may be an expression
-% involving some values that are not fixed throughout a document.
-% In this case the instance declaration may give a value in the
-% form |\DelayedEvaluation|\marg{calc expression}. In this case
-% the value is not evaluated when the instance is declared, and
-% instead the entire expression is copied to the `internal parameter
-% list' and is evaluated whenever the instance is used.
-%
-% |L| and |C| take the same value types as |l| and |c| but the internal
-% assignments are to macros not registers.
-%
-% Keys declared with |b| and |s| each take values either \emph{true} or
-% \emph{false}. if the key zzz is declared with |b| then specifying
-% |zzz=true| will essentially pass |\zzztrue| to the internal parameter
-% list (although in fact |\zzztrue| need not be defined) . If instead
-% zzz had been declared via |s|, then |zzz=true| would pass the tokens
-% of the \marg{true code} to the internal parameter list.
-%
-% If a key is specified as |x|, then when used the \emph{internal code}
-% will be copied to the internal parameter lists. This code may use |#1|
-% to denote the value supplied to the key in the instance declaration.
-% Note that this code is \emph{only} copied at the time the instance is
-% declared. It is not executed at this time. It is executed when the
-% instance is executed.\footnote{Despite the question of whether or
-% not x and g are still necessary these days, they have the wrong
-% `names' since x is the one that is not executed during delcaration
-% while g is.}
-%
-% If a key is declared with |g| then the code is run at the time the
-% instance is declared. By default \emph{nothing} is passed to the
-% internal parameter list. This code may use |#1| to denote the
-% value that will be supplied when an instance is declared.
-% Any code that should be run when an instance is executed should
-% be explicitly passed to the internal parameter list using
-% |\addto@hook\TP@toks{|\ldots|}|
-%
-% A key declared with |i|\marg{type} takes as value the name of a
-% declared instance of that type. The command token associated with
-% the key will store a command essentially equivalent to a call
-% to |\UseInstance|\marg{type}\marg{name}, but in a slightly optimised
-% internal form.
-% As an exception to this rule the replacement code may be of the form
-% |\UseTemplate| followed by the key settings for the template
-% but without the mandatory arguments. In this case the `inner'
-% instance declaration is `pre compiled' and the token assigned to
-% the store the value assigned to this key will execute an instance
-% of the template directly, it will not re-parse the keyword settings
-% each time the instance is used.
-%
-% \section{Commands}
-%
-%
-% \subsection{Template declaration commands}
-%
-% \begin{decl}
-% |\DeclareTemplateType| \marg{type}\marg{num}
-% \end{decl}
-% Declare a template type.
-%
-% \begin{decl}
-% |\DeclareTemplate|
-% \marg{type}\marg{tname}\marg{num}\marg{keyspec}\marg{code}
-% \end{decl}
-% Declare a template \meta{tname} of type \meta{type} with the set of
-% keys as defined by \meta{keyspec}. From this template instances can
-% be declared using |\DeclareInstance| At runtime such instances will run
-% \meta{code} and expect \meta{num} mandatory arguments (same number
-% for all templates of one type).\footnote{The \meta{num} argument is
-% redundent as it can be deduced from the type. However, for practical
-% reasons it seems better to keep that information with each
-% individual template declaration.}
-%
-% \begin{decl}
-% |\DeclareRestrictedTemplate|
-% \marg{type}\marg{new-tname}\marg{old-tname}\marg{keyvals}
-% \end{decl}
-% Declare as new template \meta{new-tname} for type \meta{type} by
-% taking template \meta{old-tname} as the basis and setting one or
-% more of its keys to specific values.
-%
-% \begin{decl}
-% |\DoParameterAssignments|
-% \end{decl}
-% The list of key value assignments made (and saved) during template
-% declaration is evaluated at this point in the template code.
-%
-%
-% \subsection{Instance declaration commands}
-%
-% \begin{decl}
-% |\DeclareInstance| \marg{type}\marg{iname}\marg{tname}\marg{keyvals}
-% \end{decl}
-% Declare an instance of type \meta{type} named \meta{iname} build
-% from using template \meta{tname} with key settings as given by
-% \meta{keyvals}.
-%
-% \begin{decl}
-% |\DeclareCollectionInstance|
-% \marg{collection}\marg{type}\marg{iname}\marg{tname}\marg{keyvals}
-% \end{decl}
-% Same as |\DeclareInstance| except that this instance is only active
-% when for the type \meta{type} the collection \meta{collection} was
-% selected via |\UseCollection|. E.g., within the frontmatter one
-% could make all headings behave differently by defining collection
-% instances for template type `head'.
-%
-% \subsection{Key value commands}
-%
-% \begin{decl}
-% |\DelayEvaluation|\marg{code}
-% \end{decl}
-% Used in the value spec for an instance to declare that the value
-% \meta{code} should not be evaluated at declaration time but at
-% run-time. Can also be used in the defaults for keys (given in square
-% brackets) in the declaration of templates.
-%
-% \begin{decl}
-% |\MultiSelection| \meta{counter} \marg{cases} \marg{else}
-% \end{decl}
-% Used in the value spec for an instance key to declare that the value of
-% this key depends on the current setting of \meta{counter} at run-time.
-% The \meta{cases} argument is a comma-separated list of ``values'',
-% the \meta{else} argument a single ``value''. If at run-time
-% \meta{counter} has the value $i$ then the $i$-th element of the
-% \meta{cases} list is selected. If that does not exist the
-% \meta{else} case is returned.
-%
-%
-% \subsection{Processing commands}
-%
-% \begin{decl}
-% |\UseTemplate| \marg{type}\marg{tname}\marg{keyval}
-% \end{decl}
-% Execute a template \meta{tname} of type \meta{type} at run-time
-% using \meta{keyvals} as the value assignments for its keys. In this
-% case the keys are evaluated at run-time thus this method is far
-% slower than using a predeclared instance of this template (see
-% below). This command can also appear as the value for a key of type
-% `i' in which case the evaluation happens at declaration time of the
-% template that contains this key!
-%
-%
-% \begin{decl}
-% |\UseInstance| \marg{type}\marg{iname}
-% \end{decl}
-% Run the instance \meta{iname} of template type \meta{type}. If a
-% collection is in force see if there is a collection instance of name
-% \meta{iname} and if so run that instead.
-%
-% \begin{decl}
-% |\UseCollection| \marg{type}\marg{collection}
-% \end{decl}
-% Declare that from now on (normal scoping rules) the collection
-% \meta{collection} for template type \meta{type} is in force. This
-% means that a call to |\UseInstance| will first check if there is a
-% collection instance defined, and if so use that instance, otherwise
-% use the normal instance.
-%
-%
-% \subsection{Test commands}
-%
-% \begin{decl}
-% |\IfExistsInstanceTF| \marg{type}\marg{iname}\marg{true}\marg{false}
-% \end{decl}
-% Test if for template type \meta{type} an instance with name
-% \meta{iname} exists. Select \meta{true} or \meta{false} code
-% accordingly.
-%
-%
-%
-% \section{Examples of template key types}
-%
-% The general syntax for key specification in templates (fourth argument
-% of the command |\DeclareTemplate|) is:
-%\begin{flushleft}
-%| {| \\
-%| | \meta{key-name$_1$} |=|\meta{key-type$_1$}
-% \meta{optional-default$_1$} \meta{storage-bin$_1$}|,|\\
-%| | \meta{key-name$_2$} |=|\meta{key-type$_2$}
-% \meta{optional-default$_2$} \meta{storage-bin$_2$}|,|\\
-%| ...|\\
-%| }|
-%\end{flushleft}
-% In this section we look at all possible key types and give examples
-% for them.
-%
-%
-% \subsection{Attributes that receive names as values}
-%
-% The type |n| expects to receive a \LaTeX{} name as a value. Used,
-% for example, to specify the name of a \LaTeX{} counter to use.
-%\begin{verbatim}
-% heading-id =n \heading@id,
-% counter-id =n [\DelayEvaluation{\heading@id}] \heading@counter,
-%\end{verbatim}
-% Notice the use of |\DelayEvaluation| in the default of
-% |counter-id|. It is necessary to make the default the token
-% |\heading@id| if we want to inherit the value from the |heading-id|
-% key. Otherwise it gets value of |\heading@id| at the time the
-% instance is declared.
-%
-%
-% \subsection{Attributes that receive functions as values}
-%
-%
-% The type |f|\meta{num} expects a function with \meta{num} arguments
-% as a value. The arguments are denoted by |#1|, |#2|, etc. In most
-% cases either |f0| (for declarations) or |f1| (to format one argument) are
-% needed.
-%\begin{verbatim}
-% initial-font =f0 \initial@font,
-% initial-format =f1 [#1] \initial@boxhandling,
-%\end{verbatim}
-%
-% \subsection{Attributes that receive dimensions as values}
-%
-% As far as specifying instances the |l| and |L| type behave
-% identically. They differ only in the type of internal storage-bin
-% they need: |l| expects a length register while |L| expects an
-% ordinary macro name and assigns its value via |\def|.
-%\begin{verbatim}
-% pre-sep =l \topsep,
-% post-sep =L \botsep,
-%\end{verbatim}
-%
-%
-%
-% \subsection{Attributes that receive integers as values}
-%
-% The |c| and |C| type receive integers as values. Again either of
-% them can be transparently used. In case of |c| the
-% \meta{storage-bin} has to be a \TeX{} count register not a \LaTeX{}
-% counter name, i.e., set up via |\newcount|. (\LaTeX{} counters can
-% be used as well if they are accessed via their internal name, i.e.,
-% via |\c@|\meta{\LaTeX-counter})
-%\begin{verbatim}
-% pre-penalty =c \@beginparpenalty,
-% penalty =C \hmaterial@penalty,
-%\end{verbatim}
-%
-%
-%
-% \subsection{Attributes that receive template instances as values}
-%
-% The type |i|\marg{type} takes as value the name of a declared
-% instance of that type. The \meta{storage-bin} associated with the
-% key will store a command essentially equivalent to a call to
-% |\UseInstance|\marg{type}\marg{name}, but in a slightly optimised
-% internal form.
-%
-% As an exception to this rule the replacement code may be of the form
-% |\UseTemplate| followed by the key settings for the template but
-% without the mandatory arguments. In this case the `inner' instance
-% declaration is `pre compiled' and the token assigned to the store
-% the value assigned to this key will execute an instance of the
-% template directly, it will not re-parse the keyword settings each
-% time the instance is used.
-%\begin{verbatim}
-% justification-setup =i{justification} \list@justification,
-%\end{verbatim}
-%
-% Usage within an instance declaration is either
-%\begin{verbatim}
-% justification-setup = raggedright,
-%\end{verbatim}
-% i.e., name of a declared instance or a call to |\UseTemplate|
-%\begin{verbatim}
-% justification-setup = \UseTemplate{justification}{TeX}
-% { startskip = 0pt, ... },
-%\end{verbatim}
-%
-%
-%
-% \subsection{Attributes that receive true or false values}
-%
-% The type |s| expects the strings |true| or |false| as values. In
-% this case the declaration has no \meta{storage-bin}. Instead the
-% declaration consists of two brace groups containing code. Depending
-% on the value one of the groups gets copied verbatim into the
-% internal parameter list of the instance and gets executed at
-% run-time at the point where |\DoParameterAssignments| is seen.
-%\begin{verbatim}
-% item-implicit-boolean =s
-% { \def\item@implicit@code{\item\relax} }{},
-% numbered-boolean =b [true] @heading@nums,
-%\end{verbatim}
-%
-%
-% \subsection{Attributes that accept any value}
-%
-% The type |g| is a low-level specification which contains arbitrary
-% code in place of the \meta{storage-bin}. This code is evaluated at
-% declaration time of the instance and by default \emph{nothing} is
-% passed to the internal parameter list (this has to happen explicitly
-% from within the code). |#1| may be used to access the value
-% specified.
-
-% The main purpose for this type is of historical nature (originally
-% most of the other types have been implemented internally using |g|).
-%
-% The type |x| also requires code in place of the \meta{storage-bin}.
-% However with this type all of the code is copied unevaluated to the
-% internal parameter list. There are some applications for this type
-% when implementing customisable defaults. However, it is likely that
-% it will not survive a final release.
-%\begin{verbatim}
-% generic-key =g \typeout{#1},
-% extra-assigns =x \typeout{#1},
-%\end{verbatim}
-%
-%
-%
-%
-%
-%
-% \section{A complete example}
-%
-% The following example shows a sketch of a template for typesetting
-% captions to be used as part of a larger mechanism setting whole
-% floats.\footnote{I made it up while I went along so if you spot the
-% ``missing brace'' or some other blunder tell me, FMi.}
-%
-% We declare a template type \texttt{caption} then define an example
-% template for that type and finally produce some instances from that.
-%
-% \subsection{Declaring the template type}
-%
-% To define the template type we first have to ask ourselves what
-% information would be varying each time such a template is used? A
-% potential answer could be the following:
-% \begin{itemize}
-% \item
-% The float name, e.g., `Table' or `Fig.' etc.
-% \item
-% The float
-% number e.g., `10' or `3--c' etc.
-% \item
-% The actual caption text as specified in the document.
-% \end{itemize}
-% Since the above items would be differed in each instantiation of
-% such a template we would pass them as mandatory argument to the
-% template.
-%
-% Are there others? Possibly. Here are two more that seem to be
-% useful, at least in a number of cases:
-% \begin{itemize}
-% \item
-% The text of the legend in document classes that distinguish
-% between caption text (heading to the figure/table) and legend
-% (explanatory material)
-% \item
-% Measure to which the caption should be typeset.
-% \end{itemize}
-% The last one of these might need some extra explanation. Suppose a
-% design requires that the caption width is decided depending on the
-% width of the table of figure, e.g., the caption is supposed to
-% typeset below some illustration and should not be wider than that
-% illustration, or the caption is typeset aside to the illustration
-% using the remaining space. In that case the process that formats the
-% whole float needs to communicate with the current template to pass
-% that (varying) information along. Of course, that could happen by
-% using global variables, e.g., the outer process sets the measure as
-% desired before calling the caption formatting template. What makes
-% more sense is likely to be a matter of taste but it also has to do
-% with the precise semantics of the template type. Staying with our
-% example: if the the semantics of the template type \texttt{caption}
-% is supposed to produce a formatted box (in \TeX{} terms) then we
-% should pass the measure as an argument if we ever intend to allow
-% for variations. If on the other hand the semantics are to format a
-% certain set of text into the current galley (which has measure of
-% its own) then a measure argument would not belong to this template
-% type.
-%
-% Are there other variations sensible? Yes, for example, instead of
-% passing a fixed string like ``Fig.'' as the first argument one could
-% pass an abstract float type identifier and let the template worry to
-% deduce from that information what fixed string to produce.
-%
-% Another question: why should we pass the fixed text (or an abstract
-% identifier from which it can be deduced) and the number as separate
-% arguments to the template instead of passing a combined string (like
-% it is done in the |\@makecaption| command of \LaTeXe{})? Answer:
-% because this allows to build templates that can individually
-% manipulate both bits of information, e.g., to format the number in a
-% different font, etc.
-%
-% So what are the conclusions of this discussion? Defining the
-% semantics of a template type is difficult and often needs several
-% trials to come up with something that is covering the anticipated
-% use. There is clearly not a cardinal way for defining template
-% types; how the overall separation into smaller units is done is
-% partly a matter of taste and partly a matter of the major layout
-% characteristics that one tries to support.
-%
-% Returning to our example: let's assume we settle for the first four
-% arguments, i.e., the calling template is responsible for setting the
-% measure for the caption text if necessary.
-%
-% What we also have to do is to define (at least for ourselves) what
-% data the arguments accept and what their semantics are. An informal
-% summary of that could be the following:
-% \begin{center}
-% \begin{tabular}{rrl}
-% \textit{Arg} & \textit{Data Type} & \textit{Description} \\[3pt]
-% 1 & text & fixed float description
-% \\
-% 2 & text/|\NoValue| & float number
-% \\
-% 3 & text & caption text
-% \\
-% 4 & text/|\NoValue| & legend text
-% \\
-% \end{tabular}
-% \end{center}
-% The second and the fourth argument are allowed to be missing (i.e.,
-% can get |\NoValue| passed as a value). Note that the empty string in
-% case of a text argument is different from |\NoValue|.
-%
-% We further declare that it is permissible for a template of this
-% type to ignore the information provided by all arguments except 3,
-% i.e., the caption text.
-%
-% Finally the result of the template formatting should is to typeset
-% text into a current galley (paragraph mode in \LaTeX{} lingua).
-%
-% All the above is semantic information that (at least right now) is
-% not being enforced by declaring a template type (except for the
-% number of arguments) but each template of a certain type is supposed
-% to conform to this specification nonetheless.\footnote{To make this
-% even clearer we are thinking of extending the template type
-% declaration with another argument in which one has to formally or
-% informally (?) specifies information like the one in the table
-% above.}
-%
-% This finally leads to the following declaration:
-%\begin{verbatim}
-%\DeclareTemplateType{caption}{4}
-%\end{verbatim}
-%
-% \subsection{Defining a first template}
-%
-% We start by defining a simple template of type \texttt{caption}
-% which roughly formats a caption like those being presented in
-% \LaTeXe{}'s article class, i.e., the caption is typeset as a
-% paragraph if it is longer than a single line, otherwise it is
-% centered. The legend even if present is ignored. Above and below we
-% give the designer the possibility to add some space.
-%
-% In fact the examples is more or less identical in code to
-% |\@makecaption| except that if the second argument (i.e., the
-% number) is |\NoValue| it and its preceding space\footnote{For those
-% who wonder: spaces are by default ignored within definitions when
-% the new packages are used due to a command \texttt{\textbackslash
-% IgnoreWhiteSpace}, do get a normal space one has to use
-% \texttt{\textasciitilde} and to obtain an unbreakable space
-% \texttt{\textbackslash nobreakspace}.} gets ignored.
-%
-% We start by declaring the template \texttt{toosimple} of type
-% \texttt{caption} having four mandatory arguments (as described in
-% the discussion of the template type).
-%\begin{verbatim}
-%\DeclareTemplate{caption}{toosimple}{4}
-%\end{verbatim}
-% The next argument of |\DeclareTemplate| lists all keys for the
-% template. In this case we have keys for the vertical spaces above
-% and below. We make them type |L| to save on registers but with a bit
-% of care we could also have used scratch registers like |\@tempskipa|
-% etc. Their default values are both zero.
-%\begin{verbatim}
-% {
-% above-skip =L [0pt] \caption@above@skip ,
-% below-skip =L [0pt] \caption@below@skip ,
-% }
-%\end{verbatim}
-% The final argument of |\DeclareTemplate| contains the actual
-% processing code. We start with looking at the second mandatory
-% argument (caption number) to find out if it is |\NoValue| and
-% depending on the result define a helper command |\caption@start|.
-%\begin{verbatim}
-% {
-% \IfNoValueTF{#2}
-% { \def\caption@start{#1:~} }
-% { \def\caption@start{#1~#2:~} }
-%\end{verbatim}
-% Having dealt with the prelims we now run |\DoParameterAssigments| at
-% which point the keys of the template are made available, e.g., at
-% this point all those right hand containers such as
-% |\caption@above@skip| get assigned the value specified in an
-% instantiation of the template. (That scheme allows to do preliminary
-% processing up front, e.g., defaults for the keys could be assigned
-% prior to that point in which case they are overwritten if the
-% template instance specifies a different value. the use of specifying
-% defaults via the |[..]| syntax as done above is slightly faster at
-% run-time but needs more memory.)
-%\begin{verbatim}
-% \DoParameterAssigments
-%\end{verbatim}
-% The rest of the code should look familiar to anybody who ever looked
-% at \texttt{article.cls}. The only point worth mentioning are the
-% |\relax| commands after |\caption@above@skip| and
-% |\caption@below@skip|. Since we have decided to use |L| as key type
-% these commands are macros and not registers containing the
-% dimensions as strings. This means that we have to be careful to
-% ensure that \TeX{} knows where the dimension ends. In certain cases
-% text following such a command might be mistaken as being part of the
-% dimension (e.g., if followed by the word \texttt{plus}, etc.). In
-% the code below this could only happen for the second |\vskip| but it
-% is good practice to always add a terminating |\relax| to avoid such
-% hidden traps.
-%\begin{verbatim}
-% \vskip \caption@above@skip \relax
-% \sbox \@tempboxa {\caption@start #3}
-% \ifdim \wd\@tempboxa >\hsize
-% \caption@start #3\par
-% \else
-% \global \@minipagefalse
-% \hb@xt@\hsize{\hfil\box\@tempboxa\hfil}
-% \fi
-% \vskip \caption@below@skip \relax
-% }
-%\end{verbatim}
-%
-% Why is the above template of not much use? Simply because it doesn't
-% offer any flexibility to declare different designs. The only
-% alteration offered to the designer is to modify the space above and
-% below the caption, e.g., the following declaration would mimic the
-% definition within the \texttt{article.cls} class of \LaTeXe:
-%\begin{verbatim}
-%\DeclareInstance{caption}{article}{toosimple}
-% {
-% above-skip = 0pt,
-% below-skip = 10pt,
-% }
-%\end{verbatim}
-% And that's all that can be manipulated. All items that people asking
-% to change, e.g., not having a colon after the number, using
-% different fonts and font sizes, etc.\ are still hard-wired and thus
-% inaccessible. So we have to do better if we want to make use of the
-% power the template mechanism offers.
-%
-%
-%
-% \subsection{Defining a better template}
-%
-% First step in defining better templates is to ask ourselves a couple
-% of questions:
-% \begin{itemize}
-% \item What are the main characteristics of the layout the template
-% is supposed to support?
-% \item What are the elements that we want to allow (or can allow) the
-% designer to modify?
-% \end{itemize}
-%
-% Take the first question first: the layout supported by the template
-% of the previous section had as its main characteristics that it
-% would center the caption if it would fit in a single line in the
-% current measure. We could consider this being an unchangable
-% characteristic of the layout this template produces (and a designer
-% would need to use a different template of type \texttt{caption} if a
-% design compatible with this restriction is desired) or we could try
-% to make our template smarter by adding bells and wistles that allow
-% the designer to say stuff like:
-%\begin{verbatim}
-% one-line-format = \hfil #1 \hfil,
-%\end{verbatim}
-% or
-%\begin{verbatim}
-% one-line-action = center,
-%\end{verbatim}
-% depending on how we intend to offer changing the behavior of the
-% template. Like when trying to define sensible template types we have
-% no single road to heaven (and probably as many to hell) --- it has a
-% lot to do with how we think about design.
-%
-% My advice, after having tried to work with these concepts for a
-% while, is to keep templates simple in so far as that most of not all
-% attribute for a template should be relevant for the design. In other
-% words, if you have attributes that, depending on their setting, make
-% half of the other attributes not applicable then it may be
-% appropriate to think about providing several templates instead. To
-% give an example from \LaTeXe: instead of having |\@startsection|
-% deal with both vertical heads and run-in heads provide individual
-% templates. (|\@startsection| is this famous command where design
-% switches are build in by making dimensions negative to signal
-% something and afterwards use the absolute value.)
-% Another way to look at this is to say that a template should
-% normally not contain large amounts of code which is only selected in
-% a subset of attribute settings.
-%
-% As said before there are no golden rules, it is perfectly possible
-% to make hugely complicated templates that solve every possible
-% aspect of layout one could think of in one go --- it is just that
-% with keeping it more simple one can get the same functionality with
-% less headaches for the template writer as well as the template user
-% later on.
-%
-% Returning to our example: allowing to handle the case of a single
-% line caption specially could well be considered part of the
-% template. In contrast: layouts that would put the caption number
-% sideways, i.e., which would need totally different internal coding
-% should probably be coded as a separate template of type
-% \texttt{caption}.
-%
-% So for our next example template we settle for the fixed caption
-% text plus number (if any) being at the beginning of the variable
-% caption text (coming from the document) and being together formatted
-% as some sort of a pargraph. In case of the whole caption being a
-% single line we allow the designer to specify how to lay it out
-% (e.g., centered, flush left, etc.). If there is a legend it will get
-% formatted by a vertical space followed by the legend formatted as
-% another paragraph.
-%
-% More precisely we allow for the following bells and wistles:
-%\begin{verbatim}
-%\DeclareTemplate{caption}{lesssimple}{4}
-% {
-%\end{verbatim}
-% The designer can specify the space above and below the caption like
-% we did in our first example.
-%\begin{verbatim}
-% above-skip =L [0pt] \caption@above@skip ,
-% below-skip =L [0pt] \caption@below@skip ,
-%\end{verbatim}
-% Regarding the caption number we support the case where no number is
-% present (the value being |\NoValue|) as well as the number being
-% present. For both cases the designer has to specify what formatting
-% should be attached. By default all is being typeset in the font the
-% whole caption is presented but if there is a need for it the
-% designer can use the following keys to attach special formatting
-% devices to each particular item beside specifying special spacing
-% information or replacing the default colon after the number with
-% something else.
-%\begin{verbatim}
-% number-format =f2 [#1~#2:~] \caption@number@format,
-% nonumber-format =f1 [#1:~] \caption@nonumber@format,
-%\end{verbatim}
-% If the caption is fitting onto a single line we make it possible
-% for the designer to specify how this single line should be
-% positioned (the default is to center the line).
-%\begin{verbatim}
-% single-line-format =f1 [\hfil#1\hfil] \caption@single@line@format,
-%\end{verbatim}
-% The font for the caption (including the fixed text and the number
-% unless specified differently above) is going to be the one decided
-% by the next key.
-%\begin{verbatim}
-% caption-font =f0 [\normalfont] \caption@font,
-%\end{verbatim}
-% The next attribute deserves some extra explanation: here we make use
-% of an interface which is explained in more detail when we reveil the
-% support for galley formatting.\footnote{Guess I have to apologize
-% for the fact that i partly make use of that interface in this
-% example while on other occasions (like the use of vertical spacing)
-% within the example I do not---consistency around midnight is not my
-% strength I fear (FMi).} In a nutshell the template type \texttt{hj}
-% (hyphenation \& justification) allows one to define a) the
-% justification concepts applied to the upcoming paragraphs, e.g.,
-% whether they should be set flush left, adjusted, first line
-% centered, etc.\ b) the linebreaking strategy used and c) the
-% hyphenation rules which should apply. All this is done by selecting
-% an appropriate (predefined) instance of this type as will hopefully
-% become somewhat clearer in the example instances shown below.
-%\begin{verbatim}
-% caption-hj-setup =i {hj} [default] \caption@hj@instance,
-%\end{verbatim}
-% In case there is a legend to format we give the designer the
-% possibility to specify by how much vertical space it should be
-% separated from the preceding paragraph (i.e., the caption text). The
-% attributes for font and hj setup are comparable to those for the
-% caption text itself (except that they will only apply to the
-% legend). The only addition is the key \texttt{legend-text} which is
-% allowed to take a fixed text (plus any formating and spacing for it)
-% which will be added to the front of the legend in case it is
-% provided at all (by default it is empty).
-%\begin{verbatim}
-% legend-sep =L [0pt] \caption@legend@sep ,
-% legend-text =f0 [] \caption@legend@text,
-% legend-font =f0 [\normalfont] \caption@legend@font,
-% legend-hj-setup =i {hj} [default] \caption@legend@hj@instance,
-% }
-%\end{verbatim}
-% The actual code for the template should hold few if any
-% surprises. In fact it is more or less identical to the one of the
-% first template example, except that now we have now taken out some
-% of the hardwired decisions and placed them into attributes.
-%\begin{verbatim}
-% {
-% \IfNoValueTF{#2}
-% { \def\caption@start{\caption@number@format{#1}{#2}} }
-% { \def\caption@start{\caption@nonumber@format{#1}} }
-% \DoParameterAssigments
-% \vskip \caption@above@skip \relax
-%\end{verbatim}
-% To properly measure the caption to determine if it fits a single
-% line we have to set it in the right font, so here as well as below
-% we have to apply |\caption@font|.
-%\begin{verbatim}
-% \sbox \@tempboxa {\caption@font \caption@start #3}
-% \ifdim \wd\@tempboxa >\hsize
-% \begingroup
-% \caption@font \caption@hj@instance
-% \caption@start #3\par
-% \endgroup
-% \else
-% \global \@minipagefalse
-% \hb@xt@\hsize{\caption@single@line@format{\box\@tempboxa}}
-% \fi
-%\end{verbatim}
-% To decide whether or not we have to set any legend we have to test
-% |#4| for being |\NoValue|. This part of the code was not present in
-% the previous example but otherwise should be straight forward.
-%\begin{verbatim}
-% \IfNoValueF{#4}
-% {
-% \vskip \caption@legend@sep \relax
-% \begingroup
-% \caption@legend@font \caption@legend@hj@instance
-% \caption@legend@text
-% #4\par
-% \endgroup
-% }
-% \vskip \caption@below@skip \relax
-% }
-%\end{verbatim}
-%
-% I wouldn't claim the the above template is good or contains
-% everything that would be desired and I'm sure that in the end we
-% will have several such template for typesetting the caption part and
-% perhaps decide on a different template type in the first place. So
-% this is only to give a glimpse of how the template interface could
-% be applied and I hope that reading it can see a) how they can apply
-% it to other areas as well as see what is wrong with the example
-% itself.
-%
-% To just note one point that i thought of being wrong after writing
-% the above paragraphs: the key \texttt{single-line-format} was
-% declared to be a function with one argument with the idea that
-% besides specifying the single line should be centered (|\hfil|) on
-% both sides, or flush left, or flush right (|\hfil| on one side) one
-% could also specify something like
-%\begin{verbatim}
-% single-line-format = \hspace{10pt}#1\hfil,
-%\end{verbatim}
-% that is a fixed indentation on the left in case where the caption is
-% a single line. However, of course one can't. Or at least it is not
-% safe to do so since our test in the code tests the width of the line
-% without taking into account such a finite fixed space and guess what
-% might happen? So in summary, flexibility needs some thought and
-% often some afterthoughts as well --- happy thinking :-)
-%
-%
-%
-% \subsection{Defining a few instances}
-%
-% So let us conclude this example with a few sample instances. We
-% start with one that repeats what current \LaTeXe{} provides in the
-% article class. It shows all keys with values. However in fact only
-% the first key is actually needed since all others are the same as
-% the default values in the template (and of course a legend is not
-% specifiable in standard \LaTeX{} coding so those settings simply do
-% not apply anyway).
-%\begin{verbatim}
-%\DeclareInstance{caption}{article}{lesssimple}
-% {
-% above-skip = 10pt,
-% below-skip = 0pt,
-% number-format = #1~#2:~,
-% nonumber-format = #1:~,
-% single-line-format = \hfil#1\hfil,
-% caption-font = \normalfont,
-% caption-hj-setup = default,
-% legend-sep = 0pt,
-% legend-text = ,
-% legend-font = \normalfont,
-% legend-hj-setup = default,
-% }
-%\end{verbatim}
-%
-% The next examples are taken from books on the shelf essentially a
-% random selection I fear. This one is from \emph{Introduction to
-% Database Design} by C.~J.~Date and it uses Helvetica for the caption
-% text with the caption flush left, with the figure and the fixed
-% string (e.g., `Fig.' in bold face) separated by a quad of space. No
-% legend either so this is not set up. The \texttt{hj} instance
-% \texttt{noindentflushleft} is supposed to produce a ragged right paragraph
-% without any indentation. It would have to be set up elsewhere
-% (instance to the template of type \texttt{hj}).
-%\begin{verbatim}
-%\DeclareInstance{caption}{DATE}{lesssimple}
-% {
-% above-skip = 10pt,
-% below-skip = 0pt,
-% number-format = \textbf{#1~#2}\quad,
-% nonumber-format = \textbf{#1}\quad,
-% single-line-format = #1\hfil,
-% caption-font = \fontfamily{phv} \normalfont,
-% caption-hj-setup = noindentflushleft,
-% }
-%\end{verbatim}
-%
-% The final example is from the book ``Methods of Book Design'' by
-% H.~Williamson which sets the caption centered if it fits a single
-% line but adjusted as a paragraph without any indentation if longer
-% than a single line. It uses old style numerals followed by a period
-% for the number (though the example isn't quite right as i guess the
-% text font used already has oldstyle numerals as default, so
-% |\oldstylenums| is in fact not necessary).
-%\begin{verbatim}
-%\DeclareInstance{caption}{WILLIAMSON}{lesssimple}
-% {
-% above-skip = 10pt,
-% below-skip = 0pt,
-% number-format = #1~\oldstylenums{#2}.~,
-% nonumber-format = #1~,
-% single-line-format = \hfil#1\hfil,
-% caption-font = \normalfont,
-% caption-hj-setup = noindentadjusted,
-% }
-%\end{verbatim}
-%
-%
-%
-% \section{Notes}
-%
-% \subsection{Note on multi-valued parameters}
-%
-%
-% The following code\footnote{docu taken from trial implementation in
-% xlists.dtx, FMi} implements for registers (ie L,l,C,c keys) and
-% for names (ie n key) a multi-selection mechanism of the following
-% form:
-% \begin{verbatim}
-% key = \MultiSelection \@listdepth {
-% \DelayEvaluation {2.5em},
-% 20pt + 34pt }
-% { \DelayEvaluation {1em} },
-% \end{verbatim}
-% where the first argument to |\MultiSelection| is a counter, the
-% second argument is a comma separated list of values denoting the
-% values for the cases 1, 2,\ldots, and the third argument contains
-% the value for all other cases.
-%
-% The values are evaluated at declaration time in case of registers
-% and therefore can contain calc expressions as well as
-% |\DelayEvaluation|.
-%
-% Due to the implementation the case list is not allowed to have a
-% trailing comma! And of course no checks are made whatsoever :-(
-%
-% A probably much nicer syntax would be something like this:
-% \begin{verbatim}
-% key = \MultiSelection {
-% selector = \@listdepth,
-% 1 = \DelayEvaluation {2.5em},
-% 2 = 20pt + 34pt,
-% else = \DelayEvaluation {1em}
-% },
-% \end{verbatim}
-% but i found that too difficult to implement right now.
-%
-% I think it should also be considered if this kind of thing should be
-% a generally available feature on all key types especially on the
-% f\meta{number} ones.
-%
-% Anyway it is what i need for lists right now and as such it is
-% sufficient.
-%
-%
-% \subsection{Notes on template restriction}
-%
-% Possible semantics:
-%
-% a: just:-) changes the defaults ie the new template has as
-% defaults those of its source as modified by the supplied
-% keyvals;
-%
-% b: similar to a: but also removes some keywords ie the new template
-% will not accept the keywods whose values are set by the suppied
-% keyvals;
-%
-% c: plan C.
-%
-%
-% Towards an implementation of b: but without a restriction on what
-% keys appear where.
-%
-%
-%
-%
-% \subsection{Open issues}
-%
-% In this section unresolved issues or ideas to think about and
-% perhaps implement are collected. There is no particular order to
-% them.
-%
-% \begin{itemize}
-% \item The order of arguments in |\UseCollection| is illogical in my
-% eyes! A collection typically modifies the behavior of several
-% types and thus should perhaps be first (as it is in the
-% |\DeclareCollectionInstance| case). Or not, or what?
-%
-% \item How should |\IfExistsInstanceTF| behave for Collection
-% instances? Do we need a special check for those or a default
-% action? Or do we need an additional test for the existence of
-% collection instances?
-%
-% \item It was suggested that the template type declaration should get
-% another argument in which (in?)formally the semantics for the
-% template types are described, e.g., data type of arguments,
-% resulting output, \ldots{} (somewhat like the description arguments
-% for functions and variables in Emacs-Lisp). The advantage being
-% that this helps employing the templates better as well as perhaps
-% guiding context sensitive editors to support the work with such
-% templates (e.g., providing help texts).
-%
-% \item The same might be of interest for the keys of individual
-% templates though here syntax support is already available to some
-% extend by the declaration of key types.
-%
-% \item There might be a need to distinguish between \TeX's dimen and
-% skip registers. Right now this is not done and both |l| and |L|
-% accepts what \LaTeX{} calls ``rubber length'' specifications.
-%
-% \item The type |b| can probably vanish. It is equivalent to
-% specifying the mutators of a |\newif| command in the brace groups,
-% e.g.
-%\begin{verbatim}
-% numbered-boolean =b [true] @heading@nums,
-% numbered-boolean =s [true] {\@heading@numstrue}
-% {\@heading@numsfalse},
-%\end{verbatim}
-%
-% \item See issue raised about syntax (and semantics) for
-% |\Multiselection|.
