Normative concent not used for conformance

The conformance clause only refers to section 3.3. Yet there is lots of normative content in Section 2, as well as 3.4, 3.5, etc. Isn't a BDE implementation supposed to satisfy these requirements (when applicable)? Even if some of these are captured in the schema, I assume there is a reason why they are spelled out in these additional sections. They should then be referred to by the conformance clause.
