For most purposes, Emacs doesn't have a special face type, it only has
face-names.

It's also possible to get a lisp vector containing face attributes, but
this is typically only useful for a few special tasks -- most interfaces
want a face-name).

To be reasonably compatible with Xemacs, it would be necessary to know
what exactly a face-object (such as returned by `find-face') is useful
for, and I don't.  But my guess is that a face-name is closer than a
face-vector.
