           Summary: Deleting a parentless node should be well-defined
           Product: XPath / XQuery / XSLT
           Version: Candidate Recommendation
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Update Facility
        AssignedTo: andrew.eisenberg@us.ibm.com
        ReportedBy: jonathan.robie@redhat.com

The following text occurs in the definition of upd:delete: "If $target has no
parent, the XDM instance is unchanged. An implementation may (but is not
required to) raise a dynamic error if $target had no parent before execution of
the query began. [err:XUDY0020]."

For the user, I think it is better if the standard defines what happens if we
delete a node that does not have a parent. What barriers are there to doing

If there is an insurmountable difficulty with defining this, we need to at
least say that it is implementation defined, and needs to be documented.
