Hi,

While I'm testing and browsing W3C OWL test cases, I found a strange
premise document.
The premise doc is
http://www.w3.org/2002/03owlt/equivalentProperty/premises005,
and a fragment from the doc follows.

	<owl:Restriction rdf:nodeID="d">
		<owl:onProperty rdf:resource="#p"/>
		<owl:onProperty rdf:resource="#q"/>
		<owl:hasValue rdf:resource="#v"/>
	</owl:Restriction>

According to AS&S, this looks invalid, because restrictions can have
only one
individualvaluedPropertyID or datavaluedPropertyID.

But, Jena[1] and OWL Ontology Validator[2] successfully parse the
document.
I'm confused. Any comments on this?
