In ID Match request bodies, is the container element, 'sorAttributes', necessary?

sorAttributes is used for two reasons:

1. Consistency between the Standard Request and the Forced Reconciliation Request, which have almost identical structure, but the latter adds two additional non-core schema attributes (matchRequest and referenceId).
2. It makes it clearer to the client that it is asserting a set of system of record attributes (for which it can be authoritative) and not person attributes (for which it cannot be).
