Oracle Solution for Error ora-31089

ORA-31089: schema "string

" does not target namespace "string

"

What triggered the Error:

The schema document contains references (via include and import definitions) to other schemas that do not belong to valid namespaces.

What should we do to fix it:

Make sure that all schemas 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.
