PM08107: XSLT FUNCTION TYPE-AVAILABLE COULD INCORRECTLY RETURN TRUE

APAR status

• Closed as program error.

Error description

• If called with a literal string argument, the XSLT function
  type-available would incorrectly return a true result if the
  argument was the name of one of the built-in functions defined
  in the "XQuery 1.0 and XPath 2.0 Functions and Operators"
  specification [2].
  
  For example, the expression "type-available('count')" would
  always return true because there is a built-in function called
  "fn:count", regardless of whether a type named "count" was
  available in the in-scope schema types.
