In my model, the execution order on my switch blocks have one or two numbers in curly braces following the regular notation. For example, a manual switch is annotated 0:2{2,1}. There is no mention in the documentation's table of "Sorted Order Notation" of braces.

In addition to this notation only appearing on switch blocks (in my small model), I notice that the constants associated with those switches have the same numbers as appear in braces, and are NOT numbered according to the scheme that everything at the top-level start with 0: etc.

What do the braces and unusual numbering of constant blocks mean? I have the various coders installed--is it something to do with code generation? (I hadn't seen this notation before, but I've not done very many models yet.)
