           Summary: R-084: Can final="extension" for simpleType?
           Product: XML Schema
           Version: 1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSD Part 1: Structures
        AssignedTo: ht@w3.org
        ReportedBy: sandygao@ca.ibm.com

The Datatypes rec and the Schema for Datatypes do not allow the 
value "extension" for the final attribute of a simpleType.

However, section 3.4.6 of the Structures rec (under Derivation Valid 
(Extension)) says:

2 If the {base type definition} is a simple type definition, then all of the 
following must be true: 

2.1 The {content type} must be the same simple type definition. 
2.2 The {final} of the {base type definition} must not contain extension. 
It seems that 2.2 will always be true. Is this an oversight?
