There seems to be a gap in the guidelines - this is certainly a perception of the UA group - which do not adequately deal with "dynamic HTML". There are several things that leap to mind. 1. For automatically generated websites (eg sites produced by database-backed systems, perl scripts, etc) ensure that the output is valid and accessible HTML. 2. The use of 'event' attributes (onMouseOver, onFocus, etc) can cause problems, because only some of these events have keyboard (let alone voice-input) equivalents. I think this is one that needs to be talked through with UA, PF and DOM (the groups that spring immediately to mind) but a sensible first pass would be to suggest that only those events which can be described as logical rather than device-dependent (onSubmit and onChange are the two which spring to mind, although with a little help from our friends it should be possible to expand the repertoire, and UA are dealing with this problem at the moment) should be used. 3. The future use of 'DHTML' for such joys as group editing (which is currently possible in Lotus Notes I think), very flash displays, context-sensitive information, and all those things I can't make out (even from the shoulders of the giants I ride) look likely to ensure that we need to revisit the techniques document, and the more 'technically specific' guidelines, often in consultation with the UA group at least. That gives us all more to look forward to. Charles McCathieNevile
