I'll second Jon's recommendation that you look at the WS-I Basic Profile 
for general best practices 
(http://www.ws-i.org/Profiles/Basic/2003-08/BasicProfile-1.0a.html). If 
I correctly understand what you want to do, it sounds like the best way 
may be to use the header block (SOAP doesn't actually define a footer). 
You could define one header for the request that says you want the debug 
information enabled, and a separate header for the response that 
actually provides the information.

The SOAP recommendations actually allow the use of multiple body parts, 
so you could append the debug information in the response following the 
many body element. This is not a recommended approach, though, and the 
WS-I best practices forbid it.
