I don't know of much out there that actually talks about these types of 
issues. The whole topic of header usage is still pretty much up in the 
air, though with OASIS formalizing a version of WS-Security this should 
help establish usage patterns.

Your particular requirement, to enable debug information in the request 
and have it returned in the response, is somewhat unusual in that most 
applications would not want to expose any type of internal information 
to clients. I can see where it would make sense for some environments, 
though, especially when there may be external dependencies that need to 
be tracked during the processing of requests. All I can suggest is that 
you look at the types of information you want to include and define an 
XML format to match. You might also want to try your questions about 
best practices on a mailing list for the particular framework you expect 
to be using for your services, since header processing techniques will 
differ from one framework to another.
