This has been an "issue" in the XHTML2 draft for some time:

I would be more concerned about how they are intending on making
XHTML2 compatible with XHTML1 than with the WHATWG work. For example,
XHTML2's <input> element has basically completely different semantics
than XHTML1's. Even simple elements like <img> and <q> are
incompatible across the two versions, in the current draft.
