Suggest a fix

Run the supplied CLI command with openapi-generator-cli 5.0.0-beta and the embedded userapi-1.3.0.yaml specification to reproduce the missing XML output. Trace the jaxrs-jersey generator's handling of the withXml=true option; done means generated model classes contain XML tags matching the schema's XML names.
