The objects with break-aligned-interface can't accept reference symbols 
because they _are_ the reference symbols.

Yes, this double use of break-align-symbol is a little confusing. In the 
break-aligned-interface, break-align-symbol is for naming the reference 
point. That is, a TimeSignature has break-align-symbol set to 'time-sig. 
Then, if a RehearsalMark has break-align-symbols set to '(time-sig), it will 
align itself on the TimeSignature.
