This project has a lot of work to be done.
Documentation is still difficult to follow.
The interface is somehow confusing.
It is not clear if the project is hosted on SourceForge or Github, so it is difficult to submit a issue.
Also, there are a lot of no answered issues in rt.cpan.org.
You definitely want to look for XML::Compile::SOAP for a Perl solution with you need to build/consume SOAP web services.
