[Bug 16779] New: S4S has constraint that does not allow ID constraints with "ref" attributes

https://www.w3.org/Bugs/Public/show_bug.cgi?id=16779

           Summary: S4S has constraint that does not allow ID constraints
                    with "ref" attributes
           Product: XML Schema
           Version: 1.1 only
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Structures: XSD Part 1
        AssignedTo: David_E3@VERIFONE.com

The following constraint from the Schema for Schemas assumes that all key,
unique and keyref elements have names. 

    <xs:key name="identityConstraint">
      <xs:selector xpath=".//xs:key|.//xs:unique|.//xs:keyref"/>
      <xs:field xpath="@name"/>
    </xs:key>

This is no longer a valid assumption, since they can now have the "ref"
attribute instead. I think it should be changed from key to unique, as in:

    <xs:unique name="identityConstraint">
      <xs:selector xpath=".//xs:key|.//xs:unique|.//xs:keyref"/>
      <xs:field xpath="@name"/>
    </xs:unique>
