ORA-31089: schema "string" does not target namespace "string"
Cause: The schema documentcontains references (via include and import
definitions) to other schemas that do not belong to valid namespaces.
Action: Make sure that allschemas referenced via include definitions target the
same namespace as the parent schema. Further make sure that the namespace
specified in the import definition matches the actual target namespace of the
specified schema.
