   RE: [xml-dev] Restrictions on existence of attributes?

That doesn't seem a convincing argument. Saxon says:

Validation error on line 1 column 20 of file:/c:/temp/test.xml:
  Identity constraint {uniqueAtt}: the field selects more than one node (See
  http://www.w3.org/TR/xmlschema-1/#cvc-identity-constraint clause 3)

Not exactly ideal for "end users", but it's no more obscure than the error
messages for many other validation errors.

That's an even less convincing argument. If a schema processor doesn't
conform to the spec, then don't use it.
