(My notes say add: "Not sure what reference to use for which roles have their subtrees trimmed") 24517 1 dbolter 2009-04-02 17:33:50 +0000 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. 24543 2 dbolter 2009-04-03 17:35:23 +0000 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. 25072 3 dbolter 2009-05-08 17:49:30 +0000 *** Bug 6890 has been marked as a duplicate of this bug. *** 25075 4 dbolter 2009-05-08 18:01:44 +0000 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? 25165 5 cooper 2009-05-15 12:44:38 +0000 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. 25166 6 andi.snowweaver 2009-05-15 13:39:38 +0000 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 25167 7 dbolter 2009-05-15 14:46:50 +0000 (In reply to comment #6) > 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 > Thanks! I think you need to change: "Objects with a role characteristic..." to "Children of objects with a role characteristic..." Right? 25168 8 andi.snowweaver 2009-05-15 15:11:39 +0000 I inherited the bullet from Aaron but your suggested edit makes sense. I'll "make it so". 31457 9 cooper 2010-02-04 16:42:39 +0000 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.
