ambiguous wording in conformance clause

The conformance clause reads: "SHALL implement all inheritance and semantic rules as described in [WS-Calendar-PIM] and in particular its Section 5..." Well, "in particular" seems to suggest that there are such rules in other sections than 5, but we cannot find any outside section 5 apparently. A bit confusing. Why not just say "rules in Section 5"?

Also, "Conformance rules in PIM Section 6 are applied to implementations and specifications claiming conformance to MIN" Can't we just say more clearly that these implementations and specifications must also conform to PIM V1.0 (which has its own conformance clause precisely in section 6)? Or it seems that "conformance rule" is not the same thing as parts of a conformance clause but we dont find anything described as "rule" in PIM section 6 - kind of confusing... can you clarify?
