This says that if the entire document is RDF, then the main document node
is the rdf:RDF node.  (At least I think that this is what it says.  If not,
it is saying that the main document node is rdf:RDF and then there is a
single child nore that is also rdf:RDF.)

However, Section 5.1 says that there is an alternative start production, to
be used when the content of part of a document is known to be RDF.

No inconsistency, just two different kinds of RDF-containing documents.
