I feel the discussion has not been sufficient on the merits of the 
attribute.

I disagree with this position, as I have stated before.  The attribute 
has a meaning on envelope, header, and body, in each case specifying the 
default encoding of blocks contained within.

The meaning on headers is the same as the meaning on blocks within body. 
 They are all blocks, and it is unclear why it would not be so.

We actively use it this way in SOAP 1.1, and feel that the specification 
calls for it to be used this way.

There would be a hole if the 1.2 specification were modified as proposed.
