Errors Prior to Processing
Some QDoc requests cannot be processed due to syntax errors. For example, the QDoc may not be recognized because of a misspelled name; critical attributes of the QDoc required for application processing may be invalid; or the XML may be badly formed. In such cases, a normal response based on standard naming conventions is not suitable, as the identity and contents of the QDoc are being called into question. Since QDocs are a SOAP-compliant solution, QDoc preprocessing errors are thrown back to the sender as SOAP faults. See SOAP Faults.
