The Working Group is currently focused on getting version 1.0 finished. Once
that is done we will have time to address this issue ( and others ).
Currently there is no information I can give you beyond the fact that we
recognise that co-constraints such as you describe are useful and we hope to
provide something in a later version of XML Schema.

I would guess that once we get to the design stage specific use cases would
be useful to the Working Group.
