Right.  I agree with that if a fault is not a direct child of the SOAP
body then it cannot be processed as a fault.

Whoa, my bad.  I'm not sure what I thought I was responding to.  I
agree that this addresses the example I provided when I raised the
issue; that if I want a debugging interface to "last fault generated",
I should encapsulate the fault in some neutralizing container element.

But it doesn't address the entirety of the issue that I raised, which
is; "no where is it stated how SOAP processors should recognize faults".
