I wonder how it works.  If there's a function and a variable by the
same name, how does the user tell references to which one he/she wants
to see?  Does the package have 2 different commands?  Or does it ask?
And what about looking for faces -- are those variables or functions?

The commands we have in Xref look for _identifiers_.  An identifier is
a generalization of all those different syntactic and semantic
elements: it can be a variable, a function, a structure, etc.  That
IMO is a much more convenient UI: a single command with a very short
key binding for finding any identifier.  YMMV, of course.
