i interpreted frederique's use case as 'importing' new documents,
not restoring a jackrabbit backup. i might have got him wrong though.

wrt WorkspaceImporter: i agree that it's not suited for restoring meta data,
it was not designed for this use case and IMO it's the wrong approach
as i've pointed out repeatedly. 'import' and 'restore' operations have IMO
completely different semantics.
