           Summary: [FS] automatic cast of any atomic type or just
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Formal Semantics

4.1.5 Functions calls 
The definition of []Convert(SequenceType) says to invoke 
fs:convert-simple-operand if SequenceType <: xs:anyAtomicType.
I believe that this step is supposed to implement the statement
in the XQuery language spec, section 3.1.5 "Function calls"
under the bolded phrase "function conversion rules", first
bullet, list item 2, where it says "Each item in the atomic 
sequence that is of type xdt:untypedAtomic is cast to the 
expected atomic type."  So the XQuery language spec says that
only xdt:untypedAtomic values are cast, whereas the Formal Semantics
says that any atomic type (subtype of xs:anyAtomicType)
is converted.  Personally I think the Formal Semantics is to be
prefered here, but this needs to be decided.
