This "(Obsolete)" is new.


<p class="conformance-level">A</p>

<p>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.
</p>

This note is also new. (Everything else is a revert from #2797)

<p>
Modern web technologies have standardized how user agents parse incorrect markup.
Any invalid markup is therefore allowed under 4.1.1 Parsing for technologies such as
HTML 5 and CSS 3. This success criterion is always satisfied for these technologies.
This success criterion is therefore obsolete.
</p><p>
Issues such as incorrect states or names due to a duplicate ID, or missing roles
due to inappropriately nested elements are covered by different success criteria.
</p>
</div>

<p class="note">Start and end tags that are missing a critical character in their formation, such
as a closing angle bracket or a mismatched attribute value quotation mark, are not
complete.
</p>


<p>This criterion has been removed.</p>

Note I didn't update the understanding doc. If this goes through, the understanding doc needs to be tweaked. Happy to help with that if the group's open to this solution.
