-### CMW Collections' role in composite Attester topology
-
-A CMW Collection's tree structure is not required to be a spanning tree of the system's composite Attester topology.
-If the labels carry semantic content for a Verifier (e.g. to improve Verifier performance or aid human comprehension), the collection SHOULD be integrity protected.
-For example, the collection can be integrity protected by including it in a signed token such as a CWT or JWT.
