No, it is conforming. This is used a lot on the Web for giving labels to 
Selects ("Select a country...").

WF3 will address this better, but in the meantime it's good enough.

Yes, it is. It happens sometimes, e.g. when the user has selected an 
option but later changes something and that option becomes disabled (but 
is still selected).

Yes. For size=1 controls, the first non-disabled element gets selected.

Yes. Generally the item just starts selected but then when you pick 
another option you can't select it again, I presume.
