James,

Sorry that I did not address your specific questions explicitly.
I forgot that they were there, or didn't see them :-/

It was revised extensively before its FPWD release in response to reviews, but has not yet been reviewed in its current form.  I would like to get a feeling for whether the new form of the document and rationale for its existence are satisfactory before further work on it.

I guess techniques that map easily onto existing tools are more likely to be adopted than something ad hoc that we make up.

The one at http://dvcs.w3.org/hg/prov/raw-file/863fd0c4d812/model/prov-constraints.html
addresses the blocking issue, which have been reduced to "highly encouraged" issues.

It is clear and worth doing, and is obvious why.

>> 
>> Q3.  Is the structure of PROV-C clear and appropriate?  If not, how to improve?

Yes. The meta discourse does describe how the sections tie together, but those statements are not in enough places (at top and from each section).
Solving this problem is a matter of copy and pasting.

>> 
>> Q4.  Are the instructions regarding compliance clear and appropriate (modulo several clearly-marked TODOs)?  If not, how to improve?

Yes.
