Agree in full with this... For example (i hope i don't made a mistake) the "lang" attribute was found difficoult by the screen readers that needs to change the language engine every "stranger" word and now seems that with Jaws 5.0 has been developed the first engine with full support of the "lang" attribute: this is a winner position of the WCAG guidelines that have requested to the assistive tecnologies developers to cover the "tecnology hole" of the change of language... >If the summary is null, then the test (machine or HIHR) could simply >validate for no captions and no th elements. It's simply easy to do and >IMHO makes perfect sense. If summary is null or not present then test the next lines: - if there is caption and/or there is <th> it is a data table and this is an error that "summary" is not present - if there isn't caption and/or <th> it *could* be a layout table or a wrong data table and so here there is a need of an human validator.
