Complexes of complexes

[tythomson]

Complexes are composed of other complexes. E.g., HSA-111751.1. I’m not sure that it makes sense to preserve this structure when the complex is formed. Can these be “flattened” down to a single complex of all the components? I can imagine that the current way could result in different ways to represent a complex, for example if A:A:B:B can be assembled by A:A+B:B or by A:B+A:B. If we flatten to a single complex of all components, then we might have to sort alphabetically. On the other hand, there may be complexes that have the same components, but different structures. Not sure what the correct/ideal would be here, so perhaps this is something to be figured out for the BEL specifications.
