SOAP is an interface, both client and server should use an abstraction
layer for presentation to be able to change the interface without
changing/breaking the core client application/ user experience.
XML::Compile contributes to the abstraction layer providing a HASH which
contains the message data.  Then, you can use a template to display
it to the user.  What I read in you explanation, it that you only want
to use the transport mechanism, because XSLT provides the abstraction.

It's a bit odd to put queries in Perl, and process the answers directly
with XSLT.  As first idea, it may work... but when thinking about
character-sets, error handling, validation... arggghhh, frightens me
a lot.  Of course, it is your choice (and burden)

Of course.   $trace->responseDOM

I do not believe your solution is sound on the long run, but it does
add something useful to the trace without measurable expense.  I'll
send you an intermediate version of the module, to test.
