I don't understand this notation; please explain your idea.

We discussed this in the bug list - a typo in Snippets. YOu can see  
there how it is possible to something in that way.

The problem is if one would want to fine tune it. For example, the  
Bulgarian kopanitsa 11/16 may be described as 4+3+4 where 4 = 2+2. So  
one may want to typeset the 4 as one group or one group where the  
secondary beams are grouped as 2+2. Then it is difficult to get the  
stems in say a 1+1+2 pattern to come out right.
