Months ago I tried converting a theme to HTML5, but had to give it up for the following reason: Ran into a number of validation errors with obsolete tags which are no longer supported by HTML5. Though they were all fixable but it gave me a second thought perhaps it's not such a good idea to be progressive with newer markup technology for sites that need to go live today, tomorrow, next year and that I have no control, no way to know how the site owners going to use their sites and how many plugins they will be using which have terribly markup in the template files. I can't remember exactly how many errors I encountered except this one that had me a change of heart because I am not certain of the impact on the WCAG 2.0 success criteria and how today's Screen readers handle the HTML5. W3C validator flagged Summary attribute as obsolete. Quote: "The summary attribute is obsolete. Consider describing the structure of complex tables in <caption> or in a paragraph and pointing to the paragraph using the aria-describedby attribute." So this is more a validation error than accessibility issue right? TotalValidator doesn't find it wrong. So I assume it's not an accessibility issue, or TotalValidator got it wrong. Last time I checked, browsers are buggy rendering Caption element, not sure if this is still the case but I certainly don't want to go find a hack or invent a hack to make caption element render correctly in all browsers. Aria-described attribute maybe a way to go but I don't know little about it. tee ******************************************************************* List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org *******************************************************************
