-% \begin{abstract}
-%   The |statements| package is part of the {\stex} collection, a version of {\TeX/\LaTeX}
-%   that allows to markup {\TeX/\LaTeX} documents semantically without leaving the
-%   document format, essentially turning {\TeX/\LaTeX} into a document format for
-%   mathematical knowledge management (MKM).
-%
-%   This package provides semantic markup facilities for mathematical statements like
-%   Theorems, Lemmata, Axioms, Definitions, etc. in {\stex} files. This structure can be
-%   used by MKM systems for added-value services, either directly from the {\sTeX}
-%   sources, or after translation.

-% \section{Introduction}\label{sec:intro}
-%
-% The motivation for the |statements| package is very similar to that for semantic macros
-% in the |modules| package: We want to annotate the structural semantic properties of
-% statements in the source, but present them as usual in the formatted documents. In
-% contrast to the case for mathematical objects, the repertoire of mathematical statements
-% and their structure is more or less fixed.
-%
-% This structure can be used by MKM systems for added-value services, either directly from
-% the {\sTeX} sources, or after translation. Even though it is part of the {\stex}
-% collection, it can be used independently, like it's sister package |sproofs|.
-%
-% {\stex}~\cite{Kohlhase:ulsmf08,sTeX:online} is a version of {\TeX/\LaTeX} that allows to
-% markup {\TeX/\LaTeX} documents semantically without leaving the document format,
-% essentially turning {\TeX/\LaTeX} into a document format for mathematical knowledge
-% management (MKM). Currently the {\omdoc} format~\cite{Kohlhase:OMDoc1.2} is directly
-% supported.
-% 
-% \section{The User Interface}\label{sec:user-interface}
-% 
-% The |statements| package supplies a semantically oriented infrastructure for marking up
-% mathematical statements: fragments of natural language that state properties of
-% mathematical objects, e.g. axioms, definitions, or theorems. The |statement| package
-% provides an infrastructure for marking up the semantic relations between statements for
-% the {\omdoc} transformation and uses the |ntheorem| package~\cite{MaySch:eltte09} for
-% formatting (i.e. transformation to PDF).
-%
-% \subsection{Package Options}\label{sec:user:options}
-% 
-% The |statements| package provides the \DescribeMacro{defindex}|defindex| option to
-% \sTeX. If this is set, then definienda are automatically passed into the index of the
-% document. Furthermore, the |statements| package passes the
-% \DescribeMacro{showmeta}|showmeta| to the |metakeys| package. If this is set, then the
-% metadata keys are shown (see~\cite{Kohlhase:metakeys:ctan} for details and customization
-% options). The |nontheorem| option tells statements not to load the |ntheorem| package --
-% in case some other theorem package is already loaded; e.g. by the |beamer| package and
-% we prefer that. Note that using the |nontheorem| option in a case where no theorem
-% package is loaded will lead to errors.
-%
-% \subsection{Statements}\label{sec:statements}
-% 
-% All the statements are marked up as environments, that take a |KeyVal| argument that
-% allows to annotate semantic information. Generally, we distinguish two forms of
-% statements:
-% \begin{description}
-% \item[{\twintoo{block}{statement}s}] have explicit discourse markers that delimit their
-%   content in the surrounding text, e.g. the boldface word ``{\bf{Theorem}:}'' as a start
-%   marker and a little line-end box as an end marker of a proof.
-% \item[{\twintoo{flow}{statement}s}] do not have explicit markers, they are interspersed
-%   with the surrounding text.
-% \end{description}
-% Since they have the same semantic status, they must both be marked up, but styled
-% differently. We distinguish between these two presentational forms with the
-% \DescribeMacro{display=}|display| key, which is allowed on all statement
-% environments. If it has the value |block| (the default), then the statement will be
-% presented in a paragraph of its own, have explicit discourse markers for its begin and
-% end, possibly numbering, etc. If it has the value |flow|, then no extra presentation
-% will be added the semantic information is invisible to the reader. Another key that is
-% present on all statement environments in the \DescribeMacro{id=}|id| key it allows to
-% identify the statement with a name and to reference it with the semantic referencing
-% infrastructure provided by the |sref| package~\ctancite{Kohlhase:sref}.
-%
-% \subsubsection{Axioms and Assertions}\label{sec:user:axiomassertion}
-% 
-% The \DescribeEnv{assertion}|assertion| environment is used for marking up statements
-% that can be justified from previously existing knowledge (usually marked with the
-% monikers ``Theorem'', ``Lemma'', ``Proposition'', etc. in mathematical vernacular). The
-% environment |assertion| is used for all of them, and the particular subtype of
-% assertion is given in the \DescribeMacro{type=}|type| key. So instead of
-% |\begin{Lemma}|\iffalse\end{Lemma}\fi we have to write
-% |\begin{assertion}[type=lemma]|\iffalse\end{assertion}\fi (see
-% Example~\ref{fig:assertion} for an example).
-% \begin{exfig}
-% \begin{verbatim}
-% \begin{assertion}[id=sum-over-odds,type=lemma]
-%   $\sum_{i=1}^n{2i-1}=n^2$
-% \end{assertion}
-% \end{verbatim}
-% \vspace{-1em}will lead to the result\vspace{-2em}\par\noindent
-% \begin{assertion}[id=sum-over-odds,type=lemma]
-%   $\sum_{i=1}^n{2i-1}=n^2$
-% \end{assertion}
-% \caption{Semantic Markup for a Lemma in a {\texttt{module}} context}\label{fig:assertion}
-% \end{exfig}
-%
-% Whether we will see the keyword ``Lemma'' will depend on the value of the optional
-% |display| key.  In all of the |assertion| environments, the presentation expectation is
-% that the text will be presented in italic font. The presentation (keywords, spacing, and
-% numbering) of the |assertion| environment is delegated to a theorem styles from the
-% |ntheorem| environment. For an assertion of type \meta{type} the |assertion| environment
-% calls the |ST|\meta{type}|AssEnv| environment provided by the |statements| package; see
-% Figure~\ref{fig:assertion-types} for a list of provided assertion types. Their
-% formatting can be customized by redefining the |ST|\meta{type}|AssEnv| environment via
-% the |\renewtheorem| command from the |ntheorem| package; see~\cite{MaySch:eltte09} for
-% details.

-%       (in this case the existence of a proof) is not

-% \caption{Types of Mathematical Assertions}\label{fig:assertion-types}
-% \end{exfig}
-%
-% \DescribeEnv{axiom} The |axiom| environment is similar to |assertion|, but the content
-% has a different ontological status: axioms are assumed without (formal) justification,
-% whereas assertions are expected to be justified from other assertions, axioms or
-% definitions. This environment relegates the formatting to the |STaxiomEnv| environment,
-% which can be redefined for configuration.
-% 
-% \subsubsection{Symbols}\label{sec:user:symbol}
-%
-% \DescribeEnv{symboldec} The |symboldec| environment can be used for declaring concepts
-% and symbols. Note the the |symdef| forms from the |modules| package will not do this
-% automatically (but the |definition| environment and the |\inlinedef| macro will for all
-% the definienda; see below). The |symboldec| environment takes an optional keywords
-% argument with the keys |id|, |role|, |title| and |name|. The first is for general
-% identification, the |role| specifies the {\openmath}/{\omdoc} role, which is one of
-% |object|, |type|, |sort|, |binder|, |attribution|, |application|, |constant|,
-% |semantic-attribution|, and |error| (see the {\omdoc} specification for details). The
-% |name| key specifies the {\openmath} name of the symbol, it should coincide with the
-% control sequence introduced by the corresponding |\symdef| (if one is present). The
-% |title| key is for presenting the title of this symbol as in other statements. Usually,
-% |axiom| and |symboldec| environments are used together as in Figure~\ref{fig:axioms}.
-%
-%\begin{exfig}
-% \begin{verbatim}
-% \symdef{zero}{0}
-% \begin{symboldec}[name=zero,title=The number zero,type=constant]
-%   The number zero, it is used as the base case of the inductive definition

-% \end{symboldec}
-% 
-% \symdef{succ}[1]{\prefix{s}{#1}}
-% \begin{symboldec}[name=succ,title=The Successor Function,type=application]
-%   The successor function, it is used for the step case of the inductive

-%
-% \subsubsection{Types}\label{sec:user:types}
-% 
-% In many cases, we can give additional information for symbols in the form of type
-% assignments. \sTeX does not fix a type system, but allows types to be arbitrary
-% mathematical objects that they can be defined in (imported) modules. The
-% \DescribeMacro{\symtype}|\symtype| macro can be used to assign a type to a symbol: 
-% \begin{quote}
-%   |\symtype[|\meta{keys}|]{|\meta{sym}|}{|\meta{type}|}|
-% \end{quote}
-% assigns the type \meta{type} to a symbol with name \meta{sym}. For instance
-%
-% \begin{center}%
-% |\symtype[id=plus-nat.type,system=sts]{plus}{\fntype{\Nat,\Nat}\Nat}|
-% \end{center}
-% 
-% \noindent assigns the type $\mathbb{N}\times\mathbb{N}\rightarrow\mathbb{N}$ (in the
-% |sts| type system) to the symbol |plus|. This states (type assignments are statements
-% epistemologically) that addition is a binary function on natural numbers. The |\symtype|
-% macro supports the keys |id| (for identifiers) and |system| for the type system.
-% 
-% Often, type assignments occur in informal context, where the type assignment is given by
-% a natural language sentence or phrase. For this, the |statements| package supplies the
-% \DescribeEnv{typedec}|typedec| environment and the
-% \DescribeMacro{\inlinetypedec}|\inlinetypedec| macro. Both take an optional keyval
-% argument followed by the type. The phrase/sentence is the body of the |typedec|
-% environment and the last argument of the |\inlinetypedec| macro. The symbol name is
-% given in via the |for| key. For convenience, the macro
-% \DescribeMacro{\thedectype}|\thedectype| is bound to the type. So we can use
-%\begin{verbatim}
-% \begin{typedec}[for=plus,id=plus-nat.type]{\fntype{\Nat,\Nat}\Nat}
-%   $+:\thedectype$ is a binary function on $\Nat$
-% \end{typedec}
-% \end{verbatim}
-% instead of the |\symtype| above in an informal setting. 
-% 
-% \subsubsection{Definitions, and Definienda}\label{sec:definition}
-% 
-% \DescribeEnv{definition} The |definition| environment is used for marking up
-% mathematical definitions. Its peculiarity is that it defines (i.e. gives a meaning to)
-% new mathematical concepts or objects. These\DescribeMacro{\definiendum} are identified
-% by the |\definiendum| macro, which is used as
-% |\definiendum[|\meta{keys}|]{|\meta{text}|}|. Here, \meta{text} is the text that is to
-% be emphasized in the presentation. |\definiendum| takes the key
-% \DescribeMacro{name}|name| for the optional system name of the symbol defined (for
-% reference via |\termref|, see Section~\ref{sec:user:crossref}). If the |name| key is not
-% given, then \meta{text} is used as a system name instead, which is usually sufficient
-% for most situations. The set of keys is extensible to add additional metadata for the
-% definiendum. Currently only the \DescribeMacro{lemma}|lemma| key is supported, which
-% allows to specify the base form of the name of the concept involved -- e.g. for
-% referencing in a glossary or index.
-% 
-%\begin{exfig}
-%  \def\succ#1{s(#1)}
-% \begin{verbatim}
-% \symdef{one}{1}
-% \begin{definition}[id=one.def,for=one]
-%   $\notatiendum[one]{\one}$ is the successor of $\zero$
-%   (formally: $\one :=\succ\zero$)
-% \end{definition}
-% \end{verbatim}
-% \vspace{-1em}will lead to the result\medskip\par\noindent\vspace*{-1em}
-% \begin{module}[id=onedef]
-% \importmodule{peano}
-% \symdef{one}{1}
-% \begin{definition}[id=one.def,for=one]
-%   $\notatiendum[one]{\one}$ is the successor of $\zero$
-%   (formally: $\one :=\succ\zero$)
-% \end{definition}
-% \end{module}
-% \caption{A Definition based on Figure {\ref{fig:axioms}}}\label{fig:definition}
-% \end{exfig}
-% The \DescribeMacro{defi}|\defi{|\meta{word}|}| macro combines the functionality of the
-% |\definiendum| macro with index markup from the |omdoc|
-% package~\ctancite{Kohlhase:smomdl}: For definienda where the lemma and \meta{text}
-% coincide use
-% \begin{center}
-% |\defi[|\meta{name}|]{|\meta{lemma}|}[|\meta{indexkeys}|]|
-% \end{center}
-% to markup a definiendum \meta{lemma} with system name \meta{name} that appear in the
-% index (where \meta{indexkeys} are passed to the |\omdoc@index*| macros from the |omtext|
-% package) --- in other words in almost all definitions of single-word concepts.  We also
-% have the variants \DescribeMacro{\defii}|\defii|, \DescribeMacro{\defiii}|\defiii|, and
-% \DescribeMacro{\defiv}|\defiv| for (adjectivized) multi-word compounds.  Note that if
-% the definiendum contains semantic macros, then we need to specify the |loadmodules| key
-% and also protect the semantic macro. For instance if |\eset| is the semantic macro for
-% $\emptyset$, then we would use
-% \begin{verbatim}
-% \defii[eset-comp]{$\protect\eset$}{compatible}[loadmodules]
-% \end{verbatim}
-% for the definiendum markup. 
-%
-% \begin{exfig}
-% \begin{verbatim}
-% A \defi{graph} consists of \adefi{vertices}{vertex}  and \defis{edge}. 
-% \end{verbatim}
-% \caption{Definienda where Lemma and Text Form differ}\label{fig:lemma}
-% \end{exfig}
-%
-% For the cases where the lemma and \meta{text} are different we can use the variants
-% \DescribeMacro{\adefi}|\adefi|, \DescribeMacro{\adefii}|\adefii|,
-% \DescribeMacro{\adefiii}|\adefiii|, and \DescribeMacro{\adefiv}|\adefiv| that have
-% an additional first argument that allows to specify an alternative \meta{text}; see
-% Figure~\ref{fig:defin}. The main use of these is to mark up inflected forms as in
-% Figure~\ref{fig:lemma}.
-%
-% As the greatest number of these are plurals, which tends to be regular (e.g. adding a
-% trailing ``s'' in English), we provide the variants \DescribeMacro{\defis}|\defis|,

-% \end{exfig}
-% 
-% Note that the |\definiendum|, |\defi*|, |\adefi*|, and |\defi*s|, macros can only be
-% used inside the definitional situation, i.e. in a |definition| or |symboldec|
-% environment or a |\inlinedef| macro. If you find yourself in a situation where you want
-% to use it outside, you will most likely want to wrap the appropriate text fragment in a
-% |\begin{definition}[display=flow]| ... and |\end{definition}|. For instance, we could
-% continue the example in Figure~\ref{fig:axioms} with the |definition| environment in
-% Figure~\ref{fig:definition}.
-% 
-% \DescribeMacro{\inlinedef} Sometimes we define mathematical concepts in passing, e.g. in
-% a phrase like ``\ldots $s(o)$ which we call {\textbf{one}}.''. For this we cannot use
-% the |definition| environment, which presupposes that its content gives all that is
-% needed to understand the definition. But we do want to make use of the infrastructure
-% introduced for the |definition| environment. In this situation, we just wrap the phrase
-% in an |\inlinedef| macro that makes them available. The |\inlinedef| macro accepts the
-% same |id| and |for| keys in its optional argument, and additionally the |verbalizes| key
-% which can be used to point to a full definition of the concept somewhere else.
-%
-% Note that definienda can only be referenced via a |\term| element, if they are only
-% allowed inside a named module, i.e. a |module| environment with a name given by the
-% |id=| key or the |theory=| key on is specified on the definitional environment.
-%
-% \subsubsection{Examples}\label{sec:user:example}
-% 
-% \DescribeEnv{example} The |example| environment is a generic statement environment,
-% except that the |for| key should be given to specify the identifier what this is an
-% example for. The |example| environment also expects a |type| key to be specified, so
-% that we know whether this is an example or a counterexample.
-% 
-% \DescribeMacro{\inlineex} The |\inlineex| is analogous to |\inlinedef|, only that it is
-% used for inline examples, e.g. ``\ldots mammals, e.g. goats''. Note that we have used an
-% inline example for an inline example.
-%
-%
-% \subsection{Cross-Referencing Symbols and Concepts}\label{sec:user:crossref}
-%
-% If we have defined a concept with the |\definiendum| macro, then we can mark up other
-% occurrences of the term as referring to this concept. Note that this process cannot be
-% fully automatized yet, since that would need advanced language technology to get around
-% problems of disambiguation, inflection, and non-contiguous phrases\footnote{We do have a
-%   program that helps annotate larger text collections spotting the easy cases; see
-%   {\url{http://kwarc.info/projects/stex}} and look for the program
-%   |termin|.}. Therefore, the \DescribeMacro{\termref}|\termref| can be used to make this
-% information explicit. It takes the keys
-% \begin{compactdesc}
-% \item[\texttt{cdbase}] to specify a URI (a path actually, since {\LaTeX} cannot load
-%   from URIs) where the module can be found.
-% \item[\texttt{cd}] to specify the module in which the term is defined. If the |cd| key
-%   is not given, then the current module is assumed. If no |cdbase| is specified (this is
-%   the usual case), then the CD has to be imported via a |\importmodule| from the
-%   |modules| package~\ctancite{KohAmb:smmssl}.
-% \item[\texttt{name}] to specify the name of the definiendum (which is given in the body
-%   of the |\definiendum| or the optional argument). If the |name| key is not specified,
-%   then argument of the |\termref| macro is used.
-% \item[\texttt{role}] is currently unused.
-% \end{compactdesc}
-% |\termref[cd=|\meta{cd}|,name=|\meta{name}|]{|\meta{text}|}| will just typeset the link
-% text \meta{text} with (if the |hyperref| package is loaded) a hyperlink to the
-% definition in module \meta{cd} that defines the concept \meta{name}, e.g. that contains
-% |\defi[|\meta{name}|]{|\meta{text}|}|.
-%
-% Just as the |\definiendum| macro has the convenience variants |\defi| and |\?defi*|, the
-% |\termref| has variants |\trefi|, |\trefii|, |\trefiii|, and |\trefiv| that take two and
-% three arguments for the parts of the compositum. In the same module, concepts that are
-% marked up by |\defi{|\meta{name}|}| in the definition can be referenced by
-% \DescribeMacro{\trefi}|\trefi{|\meta{name}|}|. Here the link text is just
-% \meta{name}. Concepts defined via |\defii{|\meta{first}|}{|\meta{second}|}| can be
-% referenced by \DescribeMacro{\trefii}|\trefii{|\meta{first}|}{|\meta{second}|}| (with
-% link text ``\meta{first} \meta{second}'') and analogously for
-% |\defiii|/\DescribeMacro{\trefiii}|\trefiii| and % |\defiv|/\DescribeMacro{\trefiv}|\trefiv|.
-% 
-% We have variants \DescribeMacro{\atref*}|\atrefi|, |\atrefii|, |\atrefiii|, and 
-% |\atrefiv| with alternative link text. For instance
-% |\atrefii{|\meta{text}|{|\meta{first}|}{|\meta{second}|}| references a concept
-% introduced by |\defii{|\meta{first}|}{|\meta{second}|}| but with link text \meta{text}.
-% Of course, if the system identifier is given explicitly in the optional argument of the
-% definition form, as in |\defii[|\meta{name}|]{|\meta{first}|}{|\meta{second}|}|, then
-% the terms are referenced by |\trefi{|\meta{name}|}|.
-% 
-% For referencing terms outside the current module, the module name can be specified in
-% the first optional argument of the |\*tref*| macros. To specify the |cdbase|, we have to
-% resort to the |\termref| macro with the keyval arguments.
-%
-% Note that the |\termref| treatment above is natural for ``concepts'' declared by the
-% |\termdef| macro from the |modules| package~\ctancite{KohAmb:smmssl}. Concepts are
-% natural language names for mathematical objects. For ``symbols'', i.e. symbolic
-% identifiers for mathematical objects used in mathematical formulae, we use the |\symdef|
-% macro from the |modules| package. Sometimes, symbols also have an associated natural
-% language concept, and we want to use the symbol name to reference it (instead of
-% specifying |cd| and |name| which is more inconvenient). For this the |statements|
-% package supplies the \DescribeMacro{\symref}|\symref| macro. Like |\termref|, and
-% invocation of |\symref{|\meta{cseq}|}{|\meta{text}|}| will just typeset \meta{text} with
-% a hyperlink to the relevant definition (i.e. the one that has the declaration
-% |for=|\meta{cseq} in the metadata argument.)
-% 
-% The \DescribeMacro{\term}|\term| macro is a variant of the |\termref| macro that marks
-% up a phrase as a (possible) term reference, which does not have a link \emph{yet}. This
-% macro is a convenient placeholder for authoring, where a |\termref| annotation is
-% (currently) too tedious or the link target has not been authored yet. It facilitates
-% lazy flexiformalization workflows, where definitions for mathematical concepts are
-% supplied or marked up by need (e.g. after a |grep| shows that the number of |\term|
-% annotations of a concept is above a threshold). Editors or active documents can also
-% support the |\term| macro like a wiki-like dangling link: a click on
-% |\term{|\meta{phrase}|}| could generate a new editor buffer with a stub definition (an
-% |definition| environment with |\definiendum| macro and appropriate metadata).\ednote{MK:
-% we probably need multi-part variants for |?tref*|}
-% 
-% \section{Configuration of the Presentation}\label{sec:conf}
-% 
-% \DescribeMacro{\defemph} The |\defemph| macro is a configuration hook that allows to
-% specify the style of presentation of the {\index*{definiendum}}. By default, it is set to
-% |\bf| as a fallback, since we can be sure that this is always available. It can be
-% customized by  redefinition: For instance |\renewcommand{\defemph}[1]{\emph{#1}}|,
-% changes the default behavior to italics.
-%
-% \DescribeMacro{\termemph} The |\termenph| macro does the same for the style for
-% |\termref|, it is empty by default. Note the term might carry an implicit hyper-reference
-% to the defining occurrence and that the presentation engine might mark this up, changing
-% this behavior.
-%
-% \DescribeMacro{\stDMemph} The |\stDMemph| macro does the same for the style for the
-% markup of the discourse markers like ``Theorem''. If it is not defined, it is set to
-% |\bf|; that allows to preset this in the class file. \ednote{function declarations}
-% 
-% Some authors like to lowercase the semantic references, i.e. use ``axiom 2.6'' instead
-% of the default ``\sref{peano.P5}'' to refer to the last axiom in
-% Figure~\ref{fig:axioms}. This can be achieved by redefining the
-% \DescribeMacro{\STpresent}|\STpresent| macro, which is applied to the keyword of the
-% |ST*Env| theorem environments.\ednote{this does not quite work as yet, since
-%   \textbf{STpresent} is applied when the label is written. But we would really like to
-%   have it applied when the reference is constructed. But for that we need to split the
-%   label into keyword and number in package |sref|.}
-% 
-%   Finally, we provide configuration hooks in Figure~\ref{fig:hooks} for the statement
-%   types provided by the |statement| package. These are mainly intended for package
-%   authors building on |statements|, e.g. for multi-language support. The language
-%   bindings are given in the |smultiling|~\cite{KohGin:smss:svn} package not in
-%   |statements| itself.

-%
-% We declare some switches which will modify the behavior according to the package
-% options. Generally, an option |xxx| will just set the appropriate switches to true
-% (otherwise they stay false). First we have the general options: |msection| specifies
-% that theorems should be numbered in the |msection| counter provided by the |mikoslides|
-% package/class.
