   First of all, it's a pattern hint, no the |pattern| attribute. I only
brought up the |pattern| attribute for cases where the user agent
supports the |pattern| attribute, but not the |type| value of
"datetime". For those user agents, you might want to force them to us a
specific pattern when submitting dates and times to the server.

   The part you quoted, though, only has to do with pattern hints in
fallback, not the pattern attribute.

   We've already discussed why you can't put pattern hints in tooltips.
The tooltip goes away as soon as you start typing, at least in Windows.
This makes tooltips useless for pattern hints.

   No we haven't. You never even replied to the message I posted about
<altinput>. You're thing about <dataentry>, and considering I created
<altinput> specifically to address concerns you had with <dataentry>, I
find your comment a bit insulting.
