-The brace control sequences |\{| and |\}| have their own (supplementary) switch,
-which is (even) less activated by default. The reason is that after
-\csb{MTexplicitbracesobeymathxx}, they regrettably can not be used anymore as
-delimiters: |\big\{| or |\big\}| cease to function and must be replaced by
-|\big\lbrace| and |\big\rbrace|. But
-\MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTexplicitbracesobeymathxx we
-can now enjoy $\mathtt{\{a, a>b\}}$, $\mathbf{\{a, a>b\}}$, $\mathsf{\{a,
-  a>b\}}$, or even $\mathnormalbold{\{a, a>b\}}$.\footnote{this last example
-  uses the \cs{mathnormalbold} additional alphabet defined by \mst.}
-
-There is no such restriction with $($, $)$ or the brackets $[$, $]$. When used
-as delimiters though, they will become again unreactive to the math alphabets:
-the same applies to $<$ and $>$ or to any of the other characters such as the
-slashes $/$, $\backslash$, when they are used as delimiters. This is a rather
-obvious restriction except possibly for the smallest size delimiters (the
-so-called `small variants'), as all other sizes will be anyway absent from the
-text fonts. Even the small variants may not be really available in the text
-fonts: for example the standard $<$ used as a delimiter is in \LaTeX{} a
-\cs{langle}: $\langle$. With standard \LaTeX{} |$\left< x\right>$| gives
-$\langle x\rangle$.
-
-
-Actually, \mst does try to pick up most of the `small variants' in the text
-font: |$\left<x\right>$| gives $\left<x\right>$ (but |$\left<b\right>$| gives $\left<b\right>$.) If you don't like that use the
-option §nosmalldelims§ (it is indeed perhaps a bit strange to have $\left<
-  x\right>$ next to $\left< X\right>$, again before blaming me, consider using
-§nosmalldelims§.) At any rate, whether `small' or not, delimiters are not under
-the extended law of math alphabets, this is a general rule of the way \mst
-manages these things.
-
-Examples: |\mathbf{<a,b>}| gives $\mathbf{<a,b>}$. 
-|\mathbf{\left<a,b\right>}| gives $\mathbf{\left<a,b\right>}$. 
-|\mathbf{\mathopen{<}a,b \mathclose{>}}| gives $\mathbf{\mathopen{<} a,b
-  \mathclose{>}}$.
-The \LaTeX{} standard behavior for 
-|\mathbf{\mathopen{<}a,b\mathclose{>}}| is
+The braces |\{| and |\}| remain unresponsive to the alphabet changing commands
+even after \csb{MTnonlettersobeymathxx}. One must issue also
+\csb{MTexplicitbracesobeymathxx}, but it has the disadvantage that |\{| and
+|\}| become then unusable as variable-size delimiters: |\big\{| or |\big\}|
+create errors and one must make use of |\big\lbrace| and |\big\rbrace|. But
+\MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTexplicitbracesobeymathxx
+one can now enjoy $\mathtt{\{a, a>b\}}$, $\mathbf{\{a, a>b\}}$,
+$\mathsf{\{a, a>b\}}$, or even $\mathnormalbold{\{a, a>b\}}$.\footnote{this
+  last example uses the \cs{mathnormalbold} additional alphabet defined by
+  \mst.}
+
+Even with \csb{MTnonlettersobeymathxx}, the parentheses $($, $)$, brackets
+$[$, $]$, $<$ and $>$ or the slashes $/$, $\backslash$, \emph{when used as
+  left/right delimiters}, do not react to math alphabet commands. This is
+mainly explained by the fact that the text font will not contain suitable
+glyphs, hence no attempt was made to made the delimiters pick up their glyphs
+there.
+
+But \mst does try to pick up most of the `small variants' of the delimiters
+from the text font: |$\left<x\right>$| gives $\left<x\right>$ (but
+|$\left<b\right>$| gives $\left<b\right>$.) Notice that this differs from
+standard \LaTeX{} for which |$\left< x\right>$| gives $\langle x\rangle$. As
+it is perhaps a bit strange to have $\left< x\right>$ next to
+$\left< X\right>$ there is option §nosmalldelims§: with this option the
+small-sized variants of the delimiters are not modified by \mst (option
+§nosmalldelims§ has the side effect that, for the non-delimiter uses of 
+|\{, \}| 
+to be \mst-ified it is necessary to issue \csb{MTnonlettersobeymathxx} and
+\csb{MTexplicitbracesobeymathxx}.)
+
+At any rate,
+as said above, whether `small' or not, delimiters are unresponsive to
+math alphabet commands, due to technical aspects of \TeX, and the way \mst
+handles these things.
+Examples: 
+|\mathbf{<a,b>}| gives $\mathbf{<a,b>}$ (brackets do respond),
+|\mathbf{\left<a,b\right>}| gives $\mathbf{\left<a,b\right>}$ (brackets do not
+respond), |\mathbf{\mathopen{<}a,b \mathclose{>}}| gives
+$\mathbf{\mathopen{<} a,b \mathclose{>}}$ (do respond).
