[...] It is also worth noting that <caption> is a terse descriptor. @summary is a long descriptor. While <caption> will often suffice, as there are certainly some simple tables that may not need a more detailed description, the markup language should natively provide a long descriptor to provide an overview of more complex tables when needed. @summary /already/ does this and keeping it in the HTML 5 spec principles will support the vital need for backwards compatibility with existing Assistive Technology etc. > Evidence has been presented that actually not only does summary="" not > actually in practice serve the need for which it is intended well, but > that it causes extra harm to users [...] In my 5 years as an accessibility consultant for a national service provider for blind and visually impaired people I have never encountered anything like this, so that is a bold claim. > with certain sites including > information in the summary="" attribute that should be available to all > readers universally but that is, due to the use of the summary="" > attribute, in fact not available universally. Concerns about universality are valid but in this instance slightly misguided as to me the @summary attribute genuinely supports /some/ users needs very well - which is preferential to supporting everyones poorly. Even it it fails to meet the criterion of a 'Universally Designed' attribute that is not, in this case, a good enough reason to remove it. Cheers Josh
