Ok. I agree with this. However, you go on to say:

I don't see anything in either 2.3 or 2.4 that contradicts what you said 
above. This is why I was confused earlier, I guess. The bits you quoted in 
your earlier mails agreed with what you were saying should happen, and 
then you said they should change...

Are you confusing "value content attribute not specified" with the 
unrelated "no value selected"?

I suppose the following sentence (in 2.4):

| For example, radio buttons often cannot be returned to their "no value 
| selected" state.

...could be considered to be incorrect given that a radio button can be 
checked even when its value is ""; is that what you are referring to?

I don't see how these rules will affect users unless they go out of their 
way to make DTDs, in which case they deserve whatever they get.
