ORA-30937: No schema definition for 'string' (namespace 'string') in parent 'string'
Cause: The schema definition for the parent node being processed does not allow for the specified child node in its content model. Note that any typecasting via xsi:type must occur before the schema definitions for the new type can be used
Action: Only insert elements and attributes declared in the schema. Check to make sure that xsi:type (if used) is specified first
