I believe you completely that a user can do this in a customization
ODD -- I think I've done it myself. But we need a way to do this in
the <elementSpec> that defines the element in the Guidelines. That
is, we want to able able to say that element <foo> is a member of
class att.typed, and here is its value list. I'm not entirely sure
the advantage of class membership here is worth the effort, but it is
important for many elements to be able to have their own value list
for type=.
