        If you need a list of all open documents in OOo, this is little bit of
        a hassle: You need to iterate though all components at the desktop, which
        might or might not be documents.

        Additionally, you need to examine the existing documents' frames
        for sub frames, which might contain sub documents (e.g. embedded objects
        edited out-place).

        DocumentEnumeration relieves you from this hassle.
