           Summary: [XQX] complex type derivation vs substitution group
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XQueryX
        AssignedTo: jim.melton@acm.org
        ReportedBy: mrys@microsoft.com

During the review, we discussed whether we prefer one or the other. It quickly 
showed, that there are use cases and needs for both. E.g., complex type 
derivation is easier to map with popular type to object model mappers while 
substitution provides for better XPath discoverability of the information.

We propose (after talking to one of the editors) that the spec should provide 
both approaches with some guidelines on when one may be preferable over the 
other and provide a transform between them (as it was available in previous 
internal drafts)
