On a different point, I was wondering about adaptation policies for mapping from the abstract UI layer to the concrete UI layer. One idea that I believe Rhys floated was to extend DIAL with new markup for concrete UI constructs, e.g. panels, radio buttons, tabbed controls, sliders and the like. Authoring at such a level would still be a nuisance as you would have to deal with the mixing of different levels of abstraction. It would therefore seem like a good idea to explore how adaptation policies can map between levels of abstraction in a way that simplifies the author's task by keeping the layers separated. XSLT offers one such route e.g. when combined with the XPath access functions for the delivery context. Have you explored using XSLT as a means to translate between levels of abstraction, and if so could you please offer us comments on your experience? I am also interested in going beyond XPath's simple declarative event handlers to a richer description of application behavior that takes into account an explicit model of application tasks. SCXML seems very promising, and I am looking for reports on work on using XML for dialogue modeling as part of layered descriptions of UI. p.s. this is all stuff we need to cover in the wiki.
