 #### DSSE
 
-A DSSE envelope can contain arbitrary payloads. Currently Sigstore clients only process the
-payload type `"application/vnd.in-toto+json"`. Verifiers must verify that the payload type is a
-supported and expected type. DSSE envelopes contained in a Sigstore Bundle must only contain a
-single signature (the DSSE spec allows multiple).
+The DSSE envelope in a Sigstore Bundle must conform to the [in-toto Envelope layer specification](https://github.com/in-toto/attestation/blob/main/spec/v1/envelope.md) where `payloadType` is `"application/vnd.in-toto+json"` and the payload is an [in-toto statement](https://github.com/in-toto/attestation/blob/main/spec/v1/statement.md). DSSE envelopes in a Sigstore Bundle must also contain only a single signature (the DSSE spec allows multiple).
