5.5 Testing Authority needs to update a DPP

Some of the claims in a DPP require authentication by an independent Testing Authority. Once the Testing Authority completes its work, it updates a DPP by adding a DataElement with a digital signature. This is done using the EN 18222:2026 defined API. The UACloudLibrary will save the original serialized from of a DataElement (i.e. JSON-LD with a Signature). The Signature is represented with the VerifiableCredentialType, which can be attached as an Add-In to any DataElement.
