1.1 requirements - orthogonality between elements and attributes

A number of features of XML Schema 1.0 element content models are not
available for attributes.For instance, substitution groups, or the ability
to use a <choice> to force one or another attribute to appear. These
non-orthogonalities may lead language designers to use elements in their
design where they might otherwise have preferred to use attributes.

My suggested requirement is that 1.1 eliminate as many of these
non-orthogonalities as is practicable.

Cheers,
