           Summary: [FS] technical: 4.1.5 Function Calls: free pattern in
                    not()
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2

4.1.5 Function Calls

DErr / rule (2|3|4)
"statEnv |- not (Value against Type promotes to Value')"
(rule 2 also has 'i' subscripts, no matter)
    This doesn't do what you want. The pattern Value' has no other
    occurrence in the rule, so given *any* bindings for Value and Type,
    it's easy to find a binding for Value' that makes the premise hold.
    (Never have a completely free pattern within a not()!)
