As I re-read Gregory Rosmaita's change Proposal for Summary (http://www.w3.org/html/wg/wiki/ChangeProposals/summary_element) [which came from the discussion around tables and table summaries] it strikes me that he was saying essentially the same thing (Greg?). > > Now the semantic is in a sense universal and could be in the spec, the > behaviour is not and it shouldn’t be in the spec.

I don't think it has been widely implemented yet either. Hmmm..... JF
