So this is the follow-up message.

First thing I should say is that I was wrong: The HTML5 spec does not have
any requirement for NFC at all, not even indirectly.

Second thing: So because of the first thing, the validator should not be
emitting an error for non-NFC stuff. But I think it is useful to have it to
instead have it emit a warning, and some others I've talked with who are
more knowledgeable than me about NFC agree, so what I'm going to do is, flip
the validator code to make it emit a warning instead of an error. Then I'll
update the W3C backends for the HTML5 facet and re-deploy them, by some
time early next week (which will also pull in a bunch of new and useful
changes to the backend that Henri Sivonen recently checked in upstream).
