Wouldn't this be better placed in a DTD?

By adding a fixed, pre-set attribute with the regexp to
element definitions in the DTD, you can enforce consistency.

Otherwise, can't the user just choose to use this or not,
on an individual, ad-hoc basis?

If so, what are we enforcing?

All that being said, I am of the belief that all of
this should be placed in application code. XML isn't
a solution to any problem, it is a storage and interchange 
format for applications ...

Why try to cram the entire world of computing 
science into XML?
