Situation: I have a flowservice in webmethods.io and I want it to call an on-premise service passing a document as a parameter. The document has a lot of nested fields, so recreating its format field-by-field is simply out of question. A formal XML schema is not provided in the design specification. I know it is possible to create a document using a sample of data in XML or JSON form, but I can’t rely on the data being complete - if a particular slice I try contains a null value for some field, that field won’t be recognized. Is there a way to extract an XML Schema straight from document’s description in webmethods.io?
