It is not a header block, even if it has *similar* semantics to a header 
block with
mU='true' and role='http://www.w3.org/2003/05/soap-envelope/role/ultimate
Receiver'.

The SOAP1.2 spec used to contain language that suggested that the 
SOAP:Body
had a relationship to a header block[1]. However, that language was 
removed in
subsequent drafts, e.g. [2] as a result of the discussion that Mark cited.
