Control Origination

FedRAMP accepts only one of five values for control-origination: sp-corporate, sp-system, customer-configured, customer-provided, and inherited. Hybrid choices are expressed by identifying more than one control-origination, each in a separate prop field.
For controls with a control-id ending in "-1", FedRAMP only accepts sp-corporate and sp-system.

If the control origination is inherited, there must also be a FedRAMP extension (prop name="leveraged-authorization-uuid" ns="http://fedramp.gov/ns/oscal") field containing the UUID of the leveraged authorization as it appears in the /*/system-implementation/leveraged-authorization assembly.
