Oh, and one chaser to this explanation - I want to emphasize that the 
wording in the proposed WCAG WG charter does not obligate us to change 
how we publish Techniques. It is carefully worded to *allow* us to 
change, but also allow us to keep things the same. I do agree we need 
further discussion before making any major changes like this. But 
because we have already identified problems with the current status quo, 
we do not want to be prohibited by our charter from making changes either.

So I hope everyone understands that accepting the charter as proposed 
does not force us into a particular decision with our resources. And I 
hope everyone can see the value in building flexibility on that into the 
charter, since we have to close the rechartering process up now, so that 
we can continue the discussion on our publications without undue
