For 6.1 and 6.3: Does this mean access to content in comments or content hidden by style sheets? Alternative content may not be rendered but we want users to have access to it. Thus, it may still make sense to keep two checkpoints: - Access to (rendered?) content. - Access to alternative content (and each language specifies where that comes from). For 6.6: When alternative text has been specified explicitly as empty (i.e., an empty string), render nothing. This is a rendering issue with a particular purpose. It could be considered a technique of 6.3, but I think it's probably been included as a checkpoint to ensure non-confusing rendering. > 6.7, 6.9 and 6.10 Where multiple alternatives exist, allow the user to choose > which are rendered.

One guideline talks about turning on/off, the other about (finer) control over information. Although I think on/off functionality is subsumbed by finer control, I don't think those checkpoints should be absorbed - on/off should remain separate. One reason is that on/off control is supposed to stop that which reduces accessibility, while finer control is supposed to allow greater accessibility (and no, I don't consider that the same as "reduce inaccessibility"). Thus, we are dealing with two principles and I think two guidelines could remain. - Ian -- Ian Jacobs (jacobs@w3.org) http://www.w3.org/People/Jacobs Tel/Fax: +1 212 684-1814
