73         a hassle: You need to iterate though all components at the desktop, which
74         might or might not be documents.
75 
76         Additionally, you need to examine the existing documents' frames
77         for sub frames, which might contain sub documents (e.g. embedded objects
78         edited out-place).
79 
80         DocumentEnumeration relieves you from this hassle.
