I was looking at the latest SIP schema/samples and I noticed the wsdl’s use a pattern of https://docs.oasis-open.org/legalxml-courtfiling/ns/v5.0WSDL/... For the namespace.
But the examples are importing the schema’s using a patter of https://docs.oasis-open.org/legalxml-courtfiling/ns/v5.0/WSDL/ For the namespace.
Personally I prefer the pattern used by the samples. In any case, either the service wsdl or the sample wsdl’s need to be corrected.
