David, when you say show stoppers – are you saying that these are show stoppers for putting this out for public comment as a working draft or show stoppers that must be addressed before non-working draft publication? Please let us know.
In regards to your concern with 3.2.3 -- the WCAG understanding page for SC 3.2.3 states:<http://www.w3.org/TR/UNDERSTANDING-WCAG20/consistent-behavior-consistent-locations.html>
The intent of this Success Criterion is to encourage the use of consistent presentation and layout for users who interact with repeated content within a set of Web pages and need to locate specific information or functionality more than once.
This sounds very pretty similar to what we have and thus the mobile document seems consistent with other WAI guidance – to be specific our current understanding documents do talk about consistent presentation and layout already – so the mobile document is not pushing WCAG any more than is already done.

Subject: Re: Transition Request for FPWD of Mobile Accessibility
I've read top to bottom and agree with almost everything... there are a few important issues
and a few nits
.
The important show stopper issues are:
-ambiguity about the need for keyboard alternatives for gesture actions in section 3.3 and section 4.6
-a creep on WCAG requirements for consistent navigation SC 3.2.3 in section 4.2 which could impact the meaning of 3.2.3 and 3.2.4 in WCAG
There are a few other nits that are not show stoppers for me.
A walk through with details below:
======================
I think 3.3 needs a bullet with explicit mention that every touch gesture should have a keyboard equivalent, although there is a bullet in 3.4 about this it's not clear that this is necessary for 3.3 issues in the mobile doc.
perhaps there is no mention of a keyboard equivelent requirement because of the exemption in 2.1.1
"except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints. (Level A)"
This WCAG exemption was intended for drawing programs and when the user uses a mouse to draw something...I don't think the exemption should apply to gestures even though they depend on the "user's movement between endpoints".
==================================
I think the mention of keyboard in 3.4 is a bit soft ... It says "should" rather than "must"
"Therefore, even when device manipulation gestures are provided, developers **should** still provide touch and keyboard operable alternative control options.
=====================
Section 4.2
"Components that are repeated across multiple pages should be presented in a consistent layout....Consistency between the different screen sizes and screen orientations is not a requirement under WCAG 2.0."
This infers that consist component layout is required within screen sizes.
I don't think this is quite what WCAG was getting at with SC's 3.2.3, 3.2.4.
3.2.3 was really just about left
**
navigation
**
menus, rather than components, and 3.2.4 was about labeling and identification rather than placement. I'm not saying that authors shouldn't
place other things consistently
, but I think this could lead to confusion about Consistency as it is required in WCAG
, which it isn't from my memory of those discussions and the current WCAG text.
3.2.3 Consistent Navigation: Navigational mechanisms that are repeated on multiple Web pages within a set of Web pages occur in the same relative order each time they are repeated, unless a change is initiated by the user.
3.2.4 Consistent Identification: Components that have the same functionality within a set of Web pages are identified consistently. (Level AA)
I think section 4.2 of the mobile requires some rewriting
to correct this confusion.
====================
- the following sentence about orientation is confusing to me. I read it 4 times and am still not sure what it means.
"Therefore, mobile application developers should try to support both orientations. If it is not possible to support both orientations, developers should ensure that it is easy for all users to change the orientation to return to a point at which their device orientation is support"
It's the part about "ensure that it is easy for all users to change the orientation to return to a point at which their device orientation is support"
that confuses me...
========================
4.4
This sentence confuses me
"When multiple elements perform the same action or go to the same destination (e.g. link icon with link text), these should be contained within the same actionable element. "
I guess it means, put the lined image and image text in the same anchor. But I had to read it 4 times.
================
4.5
-Conventional style: Underlined text for <add>inline</add> links, color for link
======================
4.6
"Therefore, instructions (e.g. overlays, tooltips, tutorials, etc.) should be provided to explain what gestures can be used to control a given interface and **whether** there are alternatives. "
I think the word *whether* leaves it ambiguous whether there need to be keyboard alternatives. I think WCAG requires keyboard alternatives for all gestures.
================
