"Whole hours only" is an integer. Just use that. :-)

It's a lot easier to have a type for such a common control than to have to
have to give two attributes including a precesion.

Yeah, if anyone can come up with a better name than "range" I'm all ears.

I'm not sure if you're saying that I should change the spec or not! :-)

I liked the idea of using title="" rather than a new attribute, because
then it would benefit legacy users too -- on browsers with no support for
pattern="", you still get the tooltip saying what the pattern should be.

Fair point. Fixed.

Uh huh. :-P

The problem is, which control do you put it on?

Well, checked="checked" is for back compat, and autocomplete="off" is for
back compat.

People complained about having to write required="required" in XHTML,
which is why I made it autofocus="true" instead of autofocus="autofocus".

Which do people prefer?

I've changed to to autofocus="autofocus" for now, although autofocus=""
(or "true") would also work with the current definition.

It was not allowed because actually

   <foo bar>

...is shorthand for

   <foo something="bar">

...not

   <foo bar="bar">

...despite what you might guess. So according to the previous definition,

   <input true>

...would have been equivalent to

   <input autocomplete="true">

Now, however, that the value is the same as the attribute name, the value
can be omitted.

I don't really see that it would be that useful even in those cases. You
want a whole URI for would effectively just be a big clumsy tooltip?

You misread it. The XForms "hint" attribute is "title" in HTML.

Exactly. I'm still thinking it should be removed.


Thanks for the comments!
