Hi Bruce,

glad to see the true sexy-master has entered the division...

I would go the other way around. If you have an interim template that is  
invalid, that's no big deal. When you have scrubbed it all and got  
something clean, which is what you show to the user, it should be valid.

"Disallowing" something means declaring that it is not valid HTML. It  
isn't like it stops many people from doing it, it just provides a guide to  
those who care about what they are doing, and want some help to get it  

People who know how to ajax in the magic they need are presumably capable  
of determining whether the final result is valid on their own. So if an  
intermediate step is invalid they probably decided they could live with  
that, or their tools could, or they couldn't care less - in other words  
the validity constraint there isn't important to them.
