Generally speaking, I think it's too soon to add these kind of events: 
HTML5 Forms implementations are young and I still haven't see one 
website using it.
In addition, I do not think it would be a good idea to have an event 
being sent when an element becomes valid or invalid: I do not see any 
good use case (wrt UX) that wouldn't work with the input or change 
events. What use cases do you have in mind?
Furthermore, for in-range and out-of-range, I do not believe a good 
implementation should allow the user to enter an out of range value so 
such an event might be useless. Even if, I don't see how invalid/valid 
events wouldn't fulfill the hypothetical use cases of those two.
