Possibly wrong use of RL-theorem in the Conformance spec

Hi!

In Section 2.3.1 of the Conformance spec, appended to the definition of an "OWL 2 RL entailment checker", there is the following note:

[[
Note that it follows from Theorem PR1 of Profiles [OWL 2 Profiles] 
that it is always safe for an OWL 2 RL entailment checker 
using the RDF-Based Semantics 
to return False if:
... several conditions ...
]]

But the actual theorem PR1 does only make a assertion about the relationship between the RL ruleset and the *Direct Semantics*. Nothing is said about the RDF-Based Semantics by that theorem.

So I believe that in the above note, the term "RDF-Based Semantics" has to be replaced by the term "Direct Semantics".
