july utc i didn't say that the summary attribute is not working i said that it was marked as obsolete obsolete in this instance means that browsers claiming compliance with html need not support it and people writing pages that claim compliance with html should not use it but most browsers that support html also support html not just because it will take a long time for everybody with a website to rewrite the content for html if it ever happens there are still a lot of html or compliant pages out there that would fail a conformance check for html let alone html but also because html has not yet reached the w c recommendation stage so the current stable standard is html on some discussion pages i know of at least three threads outside of user talk space there is a scaremonger going around telling people to stop using the element asap because it's marked as obsolete in html don't panic it still works in every browser i've tried it in though and will probably do so for a long time yet
