You raise a good point.  In this proposal, the binding is indeed viewed as 
separate in the sense that the processing rules of chapter 2 apply >after< 
a binding has done the job of receiving an infoset, and at an intermediary 
>before< the relayed infoset is sent by the binding.  So, in that sense 

The proposal I made is intended as a compromise.   By imposing the 
separation, we get out of the business of figuring out how to integrate 
the two.  For example, we don't have to say how a binding can munge with 
the envelope when in fact the processing rules say that >all< mU checking 
must be done before any processing is done.  What we lose is the ability 
to apply the soap extensibility and processing model to bindings.
