do you mean informative? The spec does have an informative reference.
 http://www.w3.org/2004/01/rdxh/spec#XSLT1

But there's no normative dependency, per our decision
on issue#whichlangs .

That would be like saying "2 + 2 MUST be 4". It just _is_ 4.
 (see "must is for agents" http://www.w3.org/2001/01/mp23 , which
  I should perhaps integrate into http://esw.w3.org/topic/QA/ )

Right. And actually, there's no requirement to serialize the RDF at all.
The spec just says the transformation produces an RDF graph.
