Is this a question about XML Schema, by any chance?

It's a well-known restriction in XML Schema 1.0 that the type for one
attribute/element can't depend on the value of another. There are proposals
to fix this in 1.1 - one would need a more detailed description of the rules
in your case to see whether they handle this.
