RE: WCAG 2.0 4.1.1 Parsing (elements have complete start and end tags)

I agree with James's interpretation also.  This language is not open for changes at this time but we can make sure that the understanding document helps make this clear.  If you have any suggestions for increasing the clarity, please pass them on..

"4.1.1 Parsing: In content implemented using markup languages, elements have complete start and end tags, elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique, except where the specifications allow these features. "


thanks James, that makes sense. though the wording could be clearer, while I have always considered optional end tags to be OK others have interpreted wcag as requiring them.

Steve,
The complete text is
"4.1.1 Parsing: In content implemented using markup languages, elements have complete start and end tags, elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique, except where the specifications allow these features. "

As you have stated, the html specification allows certain end tags to be optional and some have no end tags so there is no issue with 4.1.1 as the specification allows these features.

James
