DTDs, well-formed documents, and XML Schema are all expressly supported by 
XQuery.

Other schema languages can be mapped into our data model, but that requires 
someone to do the work. For RELAX-NG, that probably would involve 
specifying how the type annotations are computed, and there are some 
features of RELAX-NG, such as co-occurrence constraints, that are not 
supported in our data model.
