I believe that Leif is talking about adding a second caption element. Though technically not a _new_ element [1], using two captions on a table is not, I believe, an enhancement that will degrade gracefully with older user agents. Firefox doesn't print out the second caption, as Leif states in his change proposal, but that's not a behavior we can count on. Opera does print out the second caption. Safari and Chrome do not. IE does. NVDA says one caption when the page is loaded in Firefox. NVDA says both captions, when the page is loaded in IE. The results we will get for a second caption are unreliable. > JF > > Shelley [1] http://lists.w3.org/Archives/Public/public-html/2010Feb/0637.html
