I actually missed that in Mounir's suggestion, and the spec now rounds to 
the nearest allowed value in that case, rather than doing nothing.

Mounir: is that ok?

Mostly I agree with Mounir here, but I'm curious about what you think 
should happen for the case where there's no value, and the case where the 
control isn't a numeric/date/time type. I could see an argument for 
stepping from the default in the former case (Mounir, what do you think 
about doing that?) but for the latter case I don't really see any point 
doing anything but throw an exception, as Mounir suggested.
