Well, because, otherwise you are going outside of RDF.  (Even if you add
rules to RDF, these rules cannot forbid syntax constructions.  All they can
do is remove certain interpretations for the constructions.)

I have nothing against forbidding certain kinds of syntax, but it does
violate the ``universality'' of RDF, which some appear to be espousing.
