True, but rdf:type is not a propAttr - it has its own grammar term and
takes a URI(-reference) as value:

  [6.10] propAttr ::= typeAttr
                      | propName '="' string '"' (with embedded quotes
escaped)
  [6.11] typeAttr ::= ' type="' URI-reference '"'

see?

So rdf:type takes URI, other rdf:subject etc. things take strings,
But we know from RDF M&S, rdf:subject, rdf:predicate only take URIs
etc.  see
  http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Aug/0106.html
for rest of argument.

That is the idea
