Won't work, I don't think. Any of the elements' CM may need to say
"any element of class foo here," without enumerating members of the
foo class by name or filename -- it can't because it doesn't know
about them. It knows about classes because they are enumerated in the

I want to specify both in one declaration. It's not an accidental
coincidence that all members of a class have common attributes, it's
part of the meaning of being a part of that class. I was wondering if
there was a way to capture that in RELAX NG.
