I haven't seen that problem yet in my tests, but I will try to reproduce
it later today.

No, the RDF package enables access to RDF triples, while the DOM view
provides access to the DOM of the RDF/XML. There are many different ways
to write the same RDF triple in RDF/XML, and so working with RDF from
the DOM is quite tricky. To help with this, we built another layer for
accessing RDF triples on top of the DOM.
