There's a bit of overlap here. getModifiedDocuments only allows one note type and uses Database.ModifiedDocClass. getModifiedNoteCount allows a Set of NoteCollection.SelectOption objects.
It would make sense to consolidate them and use a single enum (not sure if this is possible, because NoteCollection.SelectOption allows more note types than ModifiedDocClass (doesn't allow things like XPages)
