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".
