Yeah the uri actually becomes the namespace for the content of the SOAP Body element. SOAP::Lite uses this to determine the module to use for an rpc/encoded request. So with your original attempt would try to load a module like cgi-bin::soap::Demo. The namespace URI doesn't have to be a URI of an actual resource and shouldn't be confused with one. This is one reason why I tend to use a URI of the form urn:Demo (which should work in your case, avoiding using the http scheme reduces the potential for confusion IMO,
