Hmmm... XSLT was designed for style sheets, not for webservices.
For example, how do you use XSLT to transform data of type <base64>?

I'd suggest that the interceptor creates a Safe compartment and unpacks
the contents of <params> into @params in that Safe compartment
(each <value> becomes a tied object that keeps track of both the type
and of the actual, unpacked value).  Then the transformations can be
specified in the form of Perl scripts which will be executed in that
Safe compartment.
