In reviewing the xlate, we have determined that a required field in the schema is not populated because the inbound message does not contain it (we are converting HL7 to XML outbound). In redefining the schema to minOccurs=”0″, the recompile work but we are still seeing the error. The message does appear to process outbound but we can’t stop the error from occuring. How can we remove the error when processing these messages?
