Most web service tools support both SOAP 1.1 and 1.2 but what should be the version to choose when building a new WS?
I’m thinking WSDL 2 wasn’t really all that adopted, but is that the case for SOAP also? Is SOAP 1.1 still considered the “de facto” standard when building SOAP web services or should SOAP 1.2 be used?
If the technology you’re using permits it, then expose endpoints with both versions of SOAP.
