Conformance clauses need to refer to sections defining aspects of conformance and do so uniformly

Some conformance clauses in ODATA CSDL have hyperlinks to other parts of CSDL and others do not. Hyperlinks are useful but explicit references to the sections in question + hyperlinks would be better. And either way, they need to be uniform for all conformance clauses.

As an editorial nit, I would number all the sub-clauses for conformance.

Another editorial nit, I would not mix must, must not and should clauses.

Need to review for consistency, see: return 501 Not Implemented for any unsupported functionality (with a hyperlink under minimal conformance) versus 501 Not Implemented for any unsupported functionality (no hyperlink under intermediate conformance)

FYI, I have not compared the content of the conformance clauses to the sections that define them for this issue.
