I'll put something like the SKOS usage into the next rev then, ... 
perhaps also noting potential future use of the OWL "deprecated" 
mechanisms, although (like DCMI) leaving terms in the namespace 
indefinitely. Also it would help clarify the spec if the proposed and 
rescinded terms were in their own part of the document, rather than all 
mixed together.

Yep, there's slightly different emphasis there. But both are variations 
on "noted"...

Yes, we've employed that kind of process before. It can work well, but 
its useful to balance it with more investigative efforts, particularly 
while SemWeb is (still) in its formative years and we're trying to 
please all of the people, all of the time. Besides in general it would 
be good to have a more complete picture of the SW deployment landscape.

Life is getting less crazy, although schedule clashes (like next week) 
still happen. Am happy to be bugged regularly about this!
