When a form is marked as novalidate, title validation messages should not be displayed and the normal title attribute should be displayed.

This is preventing the tooltip to contain the error message if the form should not be validated. For approval: it's not risky and only put some polish around a feature.

Hmm.. I'm not sure I agree with this. @novalidate is related to submission, it doesn't actually change the validity of the various elements. Things will still match :invalid etc. So since the controls are still invalid, and thus presumably should be corrected, I don't see why the tooltip is wrong? If you don't want the tooltip, why are you putting @required/@pattern/etc on the controls?

I think an author might want to set the input type to get the widget/virtual keyboard but without any validation and/or when it has it's own validation system? In addition, one of the reason why we have this tooltip is to help the users to understand what's going on with the form validation. If we are not going to validate the form, maybe we should just not annoy them? FWIW, I was thinking of disabling :-moz-ui-invalid and :-moz-ui-valid when @novalidate is set (bug 610415). But I've no strong opinion on that and I'm fine to WONTFIX that or wait after Gecko 2.0 to see what web authors want.

But we don't do any widgets, do we? And even once we do do for example a date-picker, the date-picker always selects valid values so no tooltip should be displayed.

Hmm.. I missed the part about the virtual keyboard, that's a pretty good point. The tooltip doesn't seem very critical to me, but changing that along with :-moz-ui-invalid and maybe even :invalid makes sense.

I will change :-moz-ui-valid and :-moz-ui-invalid to not apply on elements inside a @novalidate form. I don't think we can change :invalid. By the way, this let me wonder how to manage elements with no form?
