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.
