I thought that was what you meant. I agree. In fact, I would take it 
further and say that we should get rid of the assumption that every 
triple is assertible. Some triples should be seen as fragments of 
larger structures which are not even well-formed by themselves.

The restriction to binary (plus unary, ie at-most-binary) predicates 
is mildly inconvenient but quite live-with-able, I agree. That's two 
ontologists on the list.
