Very kludgy indeed.

I have one new proposal and one old one.  I'm thinking that several more
elements should be allowed at top level, namely AttDef, Choice, Sequence,
Mixed, NotationType, and EnumerationType.  These would then exist
as free-floating resources which could be referred to by idrefs
elsewhere.

The old proposal is for an AttGroup element, with a content model
of (Doc?, AttDef+), and available at top level and also within an Element
model.  This would allow multiple attributes to be treated as a
single thing for either documentation or reference.
