A couple of comments on a few of these:

IMHO this could be a valuable construct - for example the reference 
manual has an example of the list of "0 15 30 40" which is the 
possible numeric tennis scores.  Being able to name that list would 
be valuable in a system reasoning about sports statistics (which is 
one of the actual use cases in my research group - we're doing 
client-side presentation of sports information based on various 
ontologies of sport).

certainly Full must include the containers, right?  We believe all 
RDF Documents are Full (with the possible exception of those which 
abuse the owl: namespace)

The minutes from Feb 13 read [1]

so please make sure final document is congruent with this WG decision.

[1] also says

so please make sure we make the final decision congruent with this 
decision as well
