The canonical name is "co-occurrence constraints" and has been added
to XSDL 1.1 with xs:assert. If you don't want to rely on a working
draft, you can also see Schematron, the ISO standard for co-occurrence
constraints for XML. If you want xs:assert but don't want its
restrictions on XPath expressions, you can use Saxon SA (I think it
implements completely xs:assert, but with full XPath 2.0 support.)
