These are bogus warnings per HTML5 itself (Tidy is a legacy tool), and from the practical point of view, shouldn't be changed, IMO.

EDITOR'S RESPONSE: This is an Editor's Response to your comment. If you are satisfied with this response, please change the state of this bug to CLOSED. If you have additional information and would like the editor to reconsider, please reopen this bug. If you would like to escalate the issue to the full HTML Working Group, please add the TrackerRequest keyword to this bug, and suggest title and text for the tracker issue; or you may create a tracker issue yourself, if you are able to do so. For more details, see this document:
   http://dev.w3.org/html5/decision-policy/decision-policy.html

Status: Rejected
Change Description: no spec change
Rationale: As far as I can tell, these are all bogus.

useful practices in this type of situation:

- report deficiencies in test tool if incorrect results are indeed reported

- silence all erroneous reported deficiencies by substituting acceptable alternatives, so that correctly reported warnings/errors are not inadvertently overlooked

- use a better tool. :-)
