-% Another example: If we want \cs{sfrac} to produce split fractions
-% without doing anything at all, we can choose the collection
-% |plainmath|, which is defined as
-% \begin{verbatim}
-%   \DeclareCollectionInstance{plainmath}{xfrac}{mathdefault}{math}
-%     {
-%       denominator-bot-sep = 0 pt,
-%       numerator-bot-sep   = 0 pt,

-%       scaling             = false,
-%       slash-right-mkern   = 0 mu,
-%       slash-left-mkern    = 0 mu
-%     }
-% \end{verbatim}
-% This creates an alternative version of the instance |mathdefault|
-% with settings as specified by the keys. In the default math setup
-% \key{numerator-top-sep} is set to 0~pt, and here we set
-% \key{numerator-bot-sep} to 0~pt as well, so in order to avoid
-% over-specification (and an error message) we must set
-% \key{numerator-top-sep} to \cs{c_max_dim}. We activate (obeying
-% normal scoping rules) it with:
-% \begin{verbatim}
-%   \UseCollection{xfrac}{plainmath}
-% \end{verbatim}
-% Then |$\sfrac{8}{13}$| produces^^A
-% \begingroup
-%   \UseCollection{xfrac}{plainmath}
-%   $\sfrac{8}{13}$ and just typing |$8/13$| gives the same result:
-%   $8/13$.
