Hi Bob,

The complex types of DTDs are not named types in the Data Model, and that 
means that you can't match them with SequenceType in XQuery - there is no 
type annotation to match.

If RELAX NG wants to define a mapping into our Data Model, that mapping 
could produce named types. The XQuery and XSLT Working Groups have not 
produced a mapping for RELAX NG.
