[html5] Placeholder attribute on date inputs and validation

I notice from 4.10.7 that the placeholder attribute is not valid on any
of the date input types, so this produces an error at html5.validator.nu:
<label for="exin">An input:</label>
<input id="exin" type="date" placeholder="2010-06-02">
However it works just fine in Chromium 6 and Firefox 4 nightlies, and
Opera displays the date picker control . Chromium does report the
input type as being 'date' but Firefox still thinks it's 'text'.
My feeling is that if there are user agents that support the placeholder
attribute but don't display any special UI for the date input type then
using the placeholder to provide useful information to the user is
perfectly acceptable. Other than it not being valid, is there anything
else I should be concerned about?
