I too like Chuck's wording, and feel that it more precisely captures the really important acessibility issue. I think the religious issue of misusing markup should be addressed by a note for this particular checkpoint, as suggested. I actually feel that it is much more than a simple religious issue - it is also about the ability to move into the future in an accessible way. As an aside, I would personally like to see a discussion of the religi^H^H^H^H philosophy behind accessible design as an informative appendix (and would be happy to write a rant^H^H short piece) which included the ideas that accessible design is simply good design for a world where innovation is the order of the day, and that accessiblity built in from the beginning is a lot more effective than accessiblity retro-fitted. (Trying to convert large Java applications or applets from the AWT model to the more accessible swing classes is a good way to discover this, but there are many others.)

I must consider myself an agnostic, sitting on the fence. I think Ian is very close with his proposal. I agree with Eric's sentiment, but not strongly enough to have 5.3 removed entirely. I agree with Jason's sentiment, but not strongly enough to enjoin people from using tables for layout in all cases. So, here is my two cents on rewording: "If tables are used for layout (i.e you cannot yet achieve the same design using style sheets - see Guideline/checkpoint whatever) then design all layout tables so that the content is presented logically when the table is linearized." Priority 1. And by all means, add a note as per Jason's and Eric's comments: "using tables for layout is wrong, and here's why... " Perhaps Checkpoint 10.3, which as Eric points out is similar in intent, could be combined with a reworded 5.3. However, I think the caution or reminder of the difficulties caused by tables used for layout (as distinct from the specific case of columns of text) should remain in the checkpoints.
