Hi Jan,
Thanks for this.

Is it not production 6.12 we are concerned with here?

should this be 'an'?

One more test case to be clear on how an rdf:ID attribute should be interpreted.
Would you agree:
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:random="http://random.ioctl.org/#">
<rdf:Description rdf:about="http://random.ioctl.org/#bar">
<random:someProperty rdf:ID="foo" />
</rdf:Description>
</rdf:RDF>
should produce:
triple("http://random.ioctl.org/#bar", "http://random.ioctl.org/#someProperty",
literal(""))
triple("#foo", "http://www.w3.org/1999/02/22-rdf-syntax-ns#type",
"http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement")
triple("#foo",
"http://www.w3.org/1999/02/22-rdf-syntax-ns#subject","http://random.ioctl.org/#bar")
triple("#foo",
"http://www.w3.org/1999/02/22-rdf-syntax-ns#predicate","http://random.ioctl.org/#someProperty")
triple("#foo", "http://www.w3.org/1999/02/22-rdf-syntax-ns#object",literal(""))

I'd suggest this would be a good thing to do. It would be good to have
files of these test cases that folks can get straight off the web.
