@silverpill According to the Data Integrity EdDSA Cryptosuites v1.0 specification, when verifying an eddsa-jcs-2022 proof, the document's context is left as is if the proof's context does not exist. Doesn't it mean the proof can omit its context if it's signed with the same context to the document? It might be my misreading though.
