That API validates a string against a datatype specified in an object datatype(Uri, LocalName).
It mainly implements two methods :
this.datatypeAllows = function(datatype, paramList, string, context) {
and
this.datatypeEqual = function(datatype, patternString, patternContext, string, context) {
which returns a pattern Empty() if string is valid or a pattern NotAllowed(message, datatype, string) if string is invalid.
