As to my experience of developing an Java RDF parser,
the optional things of RDF are really hateful,
especially the optional rdf:RDF elements and
abbreviated syntax. 
If my understanding is right, RDF contents are mainly 
to be processed by machines rather than human. One of 
the virtues of XML is that it omits the optional
features because XML is more for machines than human.
I think RDF should be more machine-friendly than
human-friendly as well----in fact,I don't think these
options could provide more convenience than confusions
for human authors and readers.
