To understand SOAP you need to understand XML Schema. Google XML Schema
for lots of good references.
In your example, nil="true" defines the value of the element when no value
is passed.

</div>Working on a project involving the use of RXS to consume a suite of
SOAP
web services. SOAP web services with lots and lots of parameters (the
RXS templates for them run over 100 lines each). It's a project I've
worked on before; this time, I'm having to port the calls from one
server to another, with different server software, and (near as I can
tell) minor changes in the parameter tags (mostly capitalization changes).
It occurs to me that this would go a lot easier if I actually had an
adequate understanding of the syntax and low-level sematics of SOAP. For
example, one of the most puzzling things I see is that on the nulled-out
parameters in the RXS templates I have, it looks like each invocation of
nil is in its own namespace, e.g.,:
<ns1:foo xmlns:ns2="http://www.w3.org/2001/XMLSchema-instance";
ns2:nil="true"/>
<ns1:bar>.:bar:.</ns1:bar>
<ns1:baz xmlns:ns4="http://www.w3.org/2001/XMLSchema-instance";
ns4:nil="true"/>
(the names have been changed, to protect the innocent).
I'm hoping that the more I know about SOAP, the less it's going to leave
me with a bad taste in my mouth, craving some REST.
Can somebody recommend a reference and/or tutorial that will make all
this a bit more comprehensible to me?
