I don't really know.  Some object that contains all of the required
face attributes,
I'm assuming. E.g., 

(get-face 'bold)
#<face bold "Bold text.">

So basically the difference between a buffer and a buffer-name. But I haven't
looked at the C code implementing faces

I think so, as long as emacs allows a face-name everywhere a face is 
permitted.
