What I would like to see is a model of all the data being used within  
LilyPond, where each attribute and each entity is clearly and  
unambiguously  defined. This should give a clear definition of the  
properties that can be set. In a later stage this could then be  
mapped to Objects to form a process model. (At least in theory). This  
mapping might learn us when we can set those properties (using \set  
or \override).
