This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
This action item came out of the March 20 UAI TF meeting. (My notes say add: "Not sure what reference to use for which roles have their subtrees trimmed")
I checked earlier versions of the document but still could not find a section showing roles and subtree trimming. We should probably add such a section.
I talked to Aaron, this is probably about objects with a role characteristic "Children Presentational: True" in the ARIA spec. We could change the language to refer to this characteristic, or a specific related section in the ARIA spec.

Re: "4.1 Exposing supplemental interfaces: AccessibleHypertext: See 11.3.2.1? Not sure what reference to use for which roles have their subtrees trimmed. David to write up what this is about." Here is the idea: Subtree trimming When traversing the DOM in order to create and expose accessible objects, the user agent can ignore traversing down into DOM subtrees of nodes that have certain WAI-ARIA roles. See 4.2.8 of the WAI-ARIA specification for details about these roles (http://www.w3.org/WAI/PF/aria/#childrenArePresentational) Michael, where do we find which roles are childrenArePresentational?
For the moment, one can find which roles are childrenArePresentational by searching for "Children Presentational:" and identifying the ones that are "true". It would be possible to generate a list of roles for which this is the case, as an editorial action. It may be preferable to include this in a summary of characteristics of all roles as requested by comment 118 http://www.w3.org/WAI/PF/Group/comments/details?comment_id=118. I've added a cross reference in that issue.
I've already searched the ARIA spec for all roles that have "Children Presentational: True" and added them to Section 1.2 http://www.w3.org/WAI/PF/aria-implementation/#intro_treetypes

I think you need to change: "Objects with a role characteristic..." to "Children of objects with a role characteristic..." Right?
I inherited the bullet from Aaron but your suggested edit makes sense. I'll "make it so".
Removing myself from cc list, default on bug edits is to add, but I'm only acting on behalf of HTML A11Y TF which is already cc'd.
