rewrite of TOC checkpoints.

I suggest:

Remove all: TOC checkpoints.
In Guideline 13, add:

Checkpoint:  Provide a way to find conformance information

To fulfill this checkpoint, a specification MUST provide at least one 
navigation mechanism that allows the reader to locate all 
conformance-related information in the specification.

Rationale: A reader must be able to easily identify and locate all the 
information necessary to understand the conformance policy and related 
conformance information without having to read the document from cover to 
cover.  Conformance information includes: the conformance section, 
conformance clause, and material about conformance variability.  A table of 
contents entry is one way to accomplish this.

(@@ I included the last sentence in the rationale even though I believe it 
is a technique, to help clarify what is meant here.  I didn't include it in 
the checkpoint or To Fulfill, since it is a technique.
