The HTML/XHTML Test Suites are being developed by the W3C HTML Working Group (members only) as part of the W3C HTML Activity.
If you have any ideas or wish to participate to this work, your participation is welcome on the HTML test suite mailing list.
We also invite you to follow and participate to the W3C Quality Assurance (QA) Activity.
