Yes. If the OID were known, then there would be no assertion of that 
type, so logically an unknown numericoid should be equivalent to the 
non-existence of an assertion, whether in a presence filter or an 
equality, substring, etc. filter.

The question is, could the unknown oid have a known oid as a subtype? 
On reflection, I think not... that should be in the schema. So it's 
still definitive.
