I created the concept that this function implements as a common element in implementing other functions.  This is a utility function that has a clearly defined functionality, that only depends on what is considered a "composite" construct.  It is not an API function and it doesn't have to concern itself with validating the inputs, that's left to the API functions.
There are other ways to implement the breakdown of compound constructs, yours is likely another valid approach, but I've picked this one because of its flexibility.
