Couple of Qs
if ESB and DS are two nodes, I assume this will do a SOAP call and still work?
if the parameter is a complex type in the ESB message, and if I refer
to it though a XPath, will that be copied completely?
for example, if the ESB message is
<Envelope>
<Body>
<foo>
<bar>
<bar1> ... </bar1>
.....
</bar>
</foo>
</Body>
<Envelope>
Now if I refer to this as <param xpath="//foo/bar" /> .. will that
copy all its subelements as well?
