UAWG WG,

Since getting Exit Criteria approved is a long process, I'm getting it
started.

Exit Criteria are used by the W3C Director (or designate) to show that
the spec deserves to advance to the next stage of the W3C process. It is 
used to show that the spec works in the real world by showing that each 
feature is implemented in 2 independent products. Good exit criteria 
tell a convincing story that the spec is mature, complete and widely 
implemented.

I expect that a tricky issue for us will be determining what are
independent products when many products share the same rendering engine.

Here are some sample Exit Criteria:

ATAG: http://www.w3.org/TR/2013/CR-ATAG20-20131107/#exit
WCAG: http://www.w3.org/TR/2008/CR-WCAG20-20080430/#status_exit
ARIA: http://www.w3.org/TR/2011/CR-wai-aria-20110118/#sotd_exit

Note that all of these include Features At Risk, so we need to finish up 
identifying all the implementations we have of each success criteria.

Here's a proposal for a first draft of the Exit Criteria for UAAG 2.0:

----------------------------------------
Exit Criteria
The User Agent Accessibility Guidelines Working Group intends to submit
this document for consideration as a W3C Proposed Recommendation as soon
as the following conditions are met. We expect to complete testing and
show evidence of meeting all exit criteria, and change or remove the
at-risk items as needed, no earlier than @@[date]@@.

1. Define test cases: Identify a set of tests needed to cover all UAAG
normative success criteria.

2. Test Implementations: Perform these tests on multiple separate
combinations of users agents and/or user agents and extensions.

3. Verify interoperable results: Find at least two independent 
implementations of each normative success criterion.

Note on Independent Implementations:
1) Success criteria that can only be met using the rendering engine of
the user agent will need implementations of two different rendering
engines.

2) Success criteria that can only be met with the user agent user 
interface may have implementations using the same rendering engine.

2) Success criteria that can be met with an extension to the user agent
may be met with two different extensions on the same base user agent.

3) Implementations (plugins, extensions or user agents) must be from 
different code bases in order to be considered independent.
