Ian and Philippe, Fantastic! From an authoring tools perspective this is very useful. It allows a content developer to programmatically exercise the listeners individually so this has advantages to disabled as well as non-disabled users. From a disabled user perspective, the input device used to simulate the activate of each listener may be voice recogntion or some other specialized input device such as an onscreen keyboard combined with: big switch specialized keyboard (Don Johnston) Assistive technologies such as HPR could enumerate the listeners and allow the user to select which one to activate. This would aid with users creating web sites as well as accessing them. From a UI perspective a pop-up window showing the available functions to be executed in response to each event could be activated allowing the user to hear and speak which one to be activated ... and then of couse activate the appropriate one. If the WCAG group could do more with Script (require addition of function descriptions) it would be nice to have the ability to store the function description executed in response to a given event in which case a script developer could create a function description for those functions executed in response to an event that could be stored and access through the DOM. Currently DOM 3 is limited to providing the type definition. ... Perhaps for DOM 4 we could add this.

Thank you, Philippe. I'll try to gather some use cases. - Ian > [1] http://lists.w3.org/Archives/Public/www-dom/2001JulSep/0299.html -- Ian Jacobs (ij@w3.org) http://www.w3.org/People/Jacobs Tel: +1 718 260-9447
