Support for request body validation #114
Description
Following up on #113, I want to use wsdl-client, but not node-soap -- I don't love their transport choices and lack of observability.
So using wsdl-client definitions, I want (in my app) to have XSD validation of my generated request bodies as unit tests. I was thinking this might be a nice fit for wsdl-client if we do the definition-narrowing in #113. We could follow it up with a minimal-XSD generation to support the needed types for the generated operations.
wsdl-client --emitDefinitionsOnly --withOperations "Get_Workday_Companies,...." --emitMinimalXSD
would then also emit a valid XSD that could be used at app dev-time to ensure that all generated request bodies are valid without the of overhead loading the full WSDL.
