I was just reading over some historical OWL stuff, and
I was reminded of the awkward fit between some 3-ary
and 4-ary constructs in OWL, given RDF's binary limitations.

I don't see discussion of constructs like onProperty/hasValue

 Defining N-ary Relations on the Semantic Web: Use With Individuals

I think OWL follows "pattern 2"... a Restriction
works sorta like a Purchase in the example.

It seems worth pointing this out in the document.
