As an alternative to Ian's proposal: 11.2: Avoid deprecated features of W3C technologies once user agents support equivalent functionality provided by newer standards (E.G. style sheets). Priority 2. The sense of checkpoint 3.3 is that if layout and presentation are to be controlled at all by the author of the document, this must be achieved through style sheets to the extent that they are supported by user agents. This could be clarified either in a note to the checkpoint, or the Techniques document. This is already implicit in the note accompanying checkpoint 5.3 where it is recognised that style sheet positioning is not yet adequately supported and that tables may, albeit in carefully restricted circumstances, continue to be employed for purposes of layout until positioning is better implemented. However, if checkpoint 11.2 is to be changed, perhaps it will be necessary to add a further requirement that presentational elements and attributes which can not be turned off by user agents, be avoided. Absolute units of length are already discouraged elsewhere in the guidelines. Nevertheless, I remain unconvinced that a new version of the guidelines is needed so soon after Recommendation, as the issues which have been raised do not appear to be critical (Ian argued in the teleconference that style sheets could effectively be used to provide borders around images except where two images are aligned; by simply avoiding this situation in the design of the document, the problem can be avoided entirely, and although in my opinion, checkpoint 11.2 warrants clarification I don't think this issue is sufficiently serious as to warrant a new version of the document). If further problems arise, then a revised version may be warranted, but the issues which have appeared so far are not sufficiently significant to necessitate such a course of action.
