Al had some hallway conversations with members of the TAG who expressed concern as to how to interact with the HTML WG. Since we think we have a case study that reflects successful collaboration, we would like to share it more widely. ** summary PFWG and HTML WG achieved constructive collaboration at TPAC. The two factors that allowed us to do this were: (a) framing a workable topic for discussion. right-sizing (and shaping) the bite-sized topic. Find a semi-separable design tradeoff, not necessarily a single markup feature or requirement. (b) separating demand issues (user and author factors) from supply issues (markup-and-processing options). ** details (a) the topic: The topic we want to focus on here was "associating table cells with the content context on which their interpretation depends." Not just the @headers attribute; that's too small a topic because the performance against user needs depends on client processing and to some degree @headers competes with @scope. But not all table markup of interest to accessibility; that's too broad. The associations issue is sufficiently decoupled from other issues once the @scope, @headers, and browser algorithms topics are included. (b) supply and demand: Separating what the user needs in operational terms (in the user experience) from markup options allowed us to make incremental progress working from the baseline started with the thread at http:// lists.w3.org/Archives/Public/wai-xtech/2008Sep/thread.html#msg304 On Tuesday in the PFWG meeting, the HTML WG observers confirmed the PFWG participants' sense that multiple levels of context information are part of the requirement to cover real tables as they are widely used. We worked through differences in vocabulary, realizing that 'nested headers' or 'chained headers' were both ways of talking about this same phenomenon. This was progress. The PFWG participants were able to confirm the HTML WG observers' idea that "@headers pointing to TD" and "TH with @headers pointing to another TH" were both markup patterns that, married with the right sort of browser and authoring processing, could meet this requirement. This was progress. Having removed some of the spurious sources of apparent difference, we were able to report into the HTML WG meeting on Thursday a status of the issue that had some basic agreements about requirements and a plan for next-steps action. The HTML WG agreed. Al Gilman, co-chair, PFWG Janina Sajka, co-chair, PFWG Coordination note: Chris Wilson and Mike Smith, co-chairs of HTML WG have seen this and agree it is accurate. </draft>
