The use case here is to get a quick reference which elements or functions are not (jet) implemented and which extensions are available in a certain version of an XSLT 1.0 processor (in a particular browser). @Andrew: > If you'd tried to produce cut down examples, rather posting > your entire transform you would probably would have > spotted that....
