referencing common schema types

[JP Fielding]

given that a custom serialization can be performed per java object to xml, can a remote reference then be made to a schema that this xml document now represents.   for instance, DISA is making a common type registry (schema registry).  type transfer should attempt to use these.  i was wondering if it's possible to:   1) ingest a remote schema and generate a java object (EXISTENCE UNKNOWN) 2) generate a custom serialization for that object ( ALREADY EXISTS ) 3) have the WSDL generated for my service reference the remote schema as a parameter type (EXISTENCE UNKNOWN)   i know that step one can be done by hand by the user/developer.  step 2 is the type mapping concept that already exists.  what i don't know how to do, is ensure that the generated WSDL for my service references the remote schema when refering to my type.    anyone know if this is possible/how to do it?   thanks, jp
