Help needed with numbering success criteria for WCAG 2.1

Hi all,

We need to think about how we will number success criteria for WCAG 2.1. 
  We would like to ask for volunteers to look at already-proposed SC and 
spend some time thinking about how they might fit into a new version and 
propose a few options with the pros and cons for each.  We would like to 
discuss this on the July 12 or July 19 call.

Points raised already include:
People are familiar with the existing forms of the success criteria, so 
we need to decide whether to keep existing SC text as it currently 
stands and add additional SC to add to any given SC, or if we feel that 
it may be better to modify the SC text itself. We may have new 
Guidelines as well as new success criteria.  Some changes may include 
keeping SC text the same but changing the level of the SC (e.g. From AAA 
to AA) We may add SC that are at level A, AA, or AAA.  It will be 
important to think about testing and reporting tools in this process – 
will the options offered have positive or negative impact on the ability 
of tools to test and report on conformance? There is an implied 
structure to the SC in WCAG 2.0 in that all of the level A SC’s are the 
low-numbered items under each GL, AA are next, and so on.  If any AAA 
SC’s move to AA or if any AA SC’s move to A then we will be disrupting 
that implied order.  This make need to be ok, but is just another 
consideration.
So all these things need to be considered carefully. A simple wiki page 
with different options and the discussion of the pros and cons of each 
will be a sufficient deliverable for this investigation. Andrew has  set 
up a page with the basic structure for this purpose, with some options:

Anyone volunteers for working on this? With a view to making a 
recommendation to the group and facilitating a discussion on the 
findings, on the July 12th or 19th?

Thanks,
Andrew, Josh, and Michael
