Chris - at one point it was suggested that we should have a glossary 
in Guide or ref.  I think the "use with consistent meaning" below 
could be turned into one very easily, and would avoid a lot of 
comments of the type "what do you mean by XXX, we use it to mean YYY" 
(a number of which we got in public-comments) - would you be willing 
to clean this up (just make each of the below a sentence, with 
pointers) that we could either put in a document or on the web site 
as the group prefers?
