That's why I said _markup_: you don't hear caps when you speak a
natural language, so that is not needed. Now the uc/sc/lc  glyphs used
on print (should) follow rather simple rules that are dictated by
their nature, which could be specified by some markup, precisely as
you'd prefer \vector{v} to have v rendered in whatever specific style
you like for vectors. Something like natbib's \citeauthor could produce c&sc,
\Name c&lc, etc.
