Add a note to the Composition rules clarifying explicitly the meaning of having (valueset+system+filters) or (valueset+system+concept) Note: the way it works is specified by implicition in the Composition rules already but additional clarity is useful. As for all three elements in one include vs 3 includes. This is already described by the existing composition rules: * Multiple include statements are cumulative - e.g. the value set contains the union of all the includes * Within an include, all the criterion apply -e.g. the value set contains the intersection of the criterion
