That is like saying that since XML documents are intrinsically order
preserving (which they are), the RDF strategy of ignoring this
information and tunnelling unordered data-oriented structures is 
somehow wrong. If so, RDF is in good company. It's XML's job
to facilitate all kinds of interesting applications that sit on top of
it; as such the XML infoset preserves a lot of structure which
higher level apps might sometimes throw away (eg. whitespace, document
ordering, Qname internal structure). That doesn't make either wrong,
they're just different information models.
