My understanding from discussion with Jeff is that his suggestion 
that the schedule be given higher priority was provided in the 
context of an assurance that the timeline was reasonable. From 
discussion with Philippe, this is likewise my understanding of your 
discussion with him. These were prior to availability of the HTML 
Co-Chairs' decision on Issue 204: ARIA-hidden [1]. The 204 decision 
has now been available and discussed for only four days. Multiple 
aspects of the decision are under dispute, and a formal objection has 
already been filed. The problems anticipated in the extension request 
below stand as previously described, and additional concerns have emerged.

The HTML Co-Chairs' decision attempts to assert a design change on 
another W3C Working Group's specification without direct consultation 
with that group, and in spite of on-survey comments that such a 
change would not be feasible; that it would not produce the behavior 
that the Co-Chairs appear to intend; and that it would cause harm to 
existing ARIA implementations. A second formal objection, that would 
be pursued via expedited appeal, is therefore under consideration on 
this aspect. Due to participant unavailability plus time needed to 
assess the approach, PFWG will not have time to fully consider their 
approach till next week. The outcome of an appeal would have direct 
bearing on the hearing of Issue 30 as the attempt to redefine 
ARIA-describedby speaks to the question of whether there might be a 
viable alternative to longdesc.

Some portions of on-list discussion over the past few days have been 
productive with regard to clarifications and exchange of information. 
One such exchange has clarified that of the "two implementations" 
mentioned in the Co-Chairs' decision (perhaps a typo intended as "two 
implementors"), one does not exist and is therefore unavailable to be 
tested by accessibility experts. From prior communication the other 
is understood to be a partial implementation, and several 
uncertainities remain regarding potential capabilities of that 
implementation approach. There is no way to know, apart from one of 
the Co-Chairs' own assertions, that once available this 
implementation could overcome possibly unremediable flaws such as the 
disappearing cursor problem which would affect sighted users -- and 
even if so, whether it could address all of the use cases for a 
longer description mechanism for people with a variety of disabilities.

A still-unresolved question recently raised is, should the 
implementation flaw regarding the disappearing cursor in ARIA-hidden 
be solvable, whether it would then actually limit which longer 
description use cases could be met by this approach by creating other 
accessibility problems. We are not seeking to convince you of this 
point in this email, but rather seeking the time with which to more 
clearly explain certain requirements in the Issue 30 change proposal 
vis-a-vis apparent misunderstandings and questions in the Issue 204 
decision and the subsequent onlist discussion; and at the same time 
to complete assessment for, and as needed preparation of, an 
expedited appeal of a formal objection on the 204 decision.

As you yourself note above, Issue 30 is part of a dependency chain. 
The HTML Co-Chairs have asserted for over half a year that there is a 
sequential dependency between Issue 204: ARIA-hidden and Issue 30: 
Longdesc. The framing of the question on 204 and now the decision on 
it, rather than facilitating resolution of Issue 30, has left intact 
several questions critical to the fair hearing of Issue 30. Four days 
would not be reasonable to address this dependency even when not in 
the middle of one of the busiest vacation periods of the year. Our 
request for time to address the outcome of the 204 decision in the 
Issue 30 change proposal stands.
