[Calixte Denizet (:calixte)]

The xfa:datasets stream contains a xhtml node which needs to be seen as belonging to xhtml namespace in order to build correctly.
So I must add an exception in this patch:
https://github.com/mozilla/pdf.js/commit/3fa319ab0e89846d5fa90514f763449d39515843
which renders namespace-agnostic nodes under datasets and we must handle correctly this node as a all when binding data in template.
