Jeff, thanks a lot for your ideas,
In my own client I've a control over the serialization process, so this
problem is not an issue; it's when some of our customers decide to write
their own front-ends does this
problem arises, because they'll use a third-party toolkit to generate
proxies from our wsdl, and as such, they'll have no control over the way the
body of the request is formed, but in the end of the day they'll just have
to pass a complete FileInfo instance or, more likely, we'll have to add
corresponding set-methods to our web-service interface.
I guess I'll need to try to find a toolkit which might have some plug-in
ports for external XSLT modules. If I have any results , I'll come back to
this thread,
Thanks
Siarhei Biarozkin
