Roland, I agree that this is much better than just having a <purpose> element and it is consistent with XForms. Currently, platform accessiblity API on Windows (IAccessible2) and Linux allow us to provide a descrpiption of the handler which you would call <hint>. The label allows a short name for the function. We could add that capability in the platform accessibility apis. In ODF we provide short names and long descriptions (like hints) for all drawing objects and image maps links. Where this is extremely valuable is when a user, who is blind, needs to make a decision as to whether to perform an action or not - such as a purchase. Role is a type applied to objects and really does not apply to event handlers. So, if this is a proposal I support it.

However, I believe that the notion is a good one though I do not believe that it goes far enough. XForms allows three pieces of information to be associated with an action, each of which can be used in different circumstances. These are the <label>, <hint> and <help> elements [1]. The latest version of the XML Events 2 spec is lacking in examples in the Handlers section [2]. Something along the lines of the following is what I have in mind: <action id="doThis"> <label>Do This</label> <hint>performing this action will delight you.</hint> ... </action> and to allow the same ability with a script handler. . . <action id="doThat"> <label>Do That</label> <hint>performing this action will delight you.</hint>. <script type="application/x-javascript"> doactivate(event); </script> </action> [1] http://www.w3.org/TR/xforms/#ui-commonelems [2] http://www.w3.org/TR/2007/WD-xml-events-20070216/#s_handler_module_elements Regards, Roland Mark Birbeck <mark.birbeck@x-port.net> Sent by: public-xhtml2-request@w3.org To Richard Schwerdtfeger <schwer@us.ibm.com> 11/11/2007 21:53 cc public-xhtml2@w3.org, www-html-editor@w3.org Subject Re: Comment on XML 2 Events Hi Rich, Yes, I just re-read your email, and realised what you were saying. Sorry about that. However, using an element in this way sounds just like the plain text equivalent of @role, which therefore means it would probably have wider applicability than just <action>. I wonder if we should look at trying to generalise this. Any thoughts on that?
