By 'unchanged', I suppose you referred to Laura's CP: That it should be 
adopted, unchanged w.r.t. the normativity that it suggests: Longdesc as 
fully conforming, right now.

+1 Sounds like a plan. It could allow us to keep the CP roughly as is.

W.r.t. what PF should do in ARIA 1.1, then I would give them permission 
to - and give them permission to - define @longdesc as an ARIA 
attribute. That is: It should be up to PF whether to EITHER turn 
@longdesc into an ARIA attribute, OR whether to go for a a shiny new 
attribute [and simply define how @longdesc should be handled from an 
ARIA perspective]. If reused directly, then I suppose @longdesc would 
become like the @role attribute: Without any prefix. Whether it would  
be wise to reuse it, probably relies on an evaluation of the legacy. 
Priority should be an attribute that works the way we want it to work.
