The new grammar is in terms of the Infoset so cannot even distinguish
the above form; so both alternatives are allowed.

In the editors draft of the next working draft, the <rdf:RDF/> element is:
and has a possibly-empty list of content.

Although, I can't see what use an empty <rdf:RDF/> would be, it is still OK.

I hope this answers your questions
