Correct, it should provide the framework to support the keyword operations
and how they are prettified.  But prettify can be made dependent on language.
And pointed out, for tex, prettify falls short in some aspects.  The improvement
would be for prettify to handle them.  Superscript and subscripts can be handled.
Originally, TeX's symbols were considered the same way as programming language.
But that assumption is not completely correct because the construction
of mathematical expressions differs in important ways from standard programming
syntax.

Could make a minor mode for texinfo to set things up using functionality
from prog-mode.el.  The minor mode could also handle superscripts and 
subscripts.
