SiRPAC: Missing Error

The following is against RDF production 6.12 (uses both a parseType and an
about attribute):

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:a="http://example.org/a#">
<rdf:Description about="b">
  <a:c rdf:parseType="Resource" rdf:about="val">
    <a:d>text</a:d>
  </a:c> 
</rdf:Description>
</rdf:RDF>

SiRPAC should raise an error, but doesn't.

Furthermore, it seems possible that this could be set up as not being an
error (i.e. A resource is created with the URI of the about attribute).

The use of this syntax is necessary to support an RDF-icized version of RSS
0.91.
