Perl-SOAP queries

Hi,
My very first question in this list, and also my first time using SOAP/Perl
SOAP.
I have a few questions -
1. Can a request from a perl-soap client sent be only sent to a
machine/server running the server module of perl-soap ?
2. In the request I am supposed to make, the body of the soap request
contains another XLS (XML for location service) object. Can I hard code this
object into the body ?
3. How do I define multiple namespace in the header of the envelope? and
which one of them would be the default one?
4. Are there any more examples available for this SOAP package, besides the
one present in the package (test.pl) ?

Any pointers would be appreciated.

Thanks.
