Thank you for your review.

Sandro brought up a similar point. It sounds reasonable to me (the RDF 
format of manifest files does not need to be very complicated, but may be 
unfamiliar to the target audience).

The current version of the document doesn't address Core because Core 
wasn't finalized until the same time Test was to be frozen. We could do it 
now (update the document, repository, and (approved) test cases) by 
Thursday evening, I think, and then those updates should be reviewed. 

Whenever these updates are done - once we label test cases as Core, I 
think we also need to say they are PRD (as well as BLD) test cases? For 
the purpose of test cases, I was thinking to treat safe-Core as a dialect.

The decision to represent the (RIF) conclusions as RIF condition formulas 
was made because BLD defines conformance in terms of entailment of 
condition formulas and not document formulas. 

We have some residual references to conclusion "documents" in the test 
document and we should reword these if we keep conclusions as condition 

Some of the test case conclusions (e.g. 
RDF_Combination_Constant_Equivalence_Graph_Entailment_1) are not RIF, they 
are RDF.

If the method of combining is to import a constructed document, then I 
think the Local_Constant test case will be ok, because the local constant 
in the imported document will be distinct from the one in the premises

We can add something about this in section 6.

Is the test document the right place to explain why print and query aren't 
part of the standard?
