 ## Background
 The library exports normative suites for Data Integrity:
-- `checkDataIntegrityProofFormat` checks the proofs of VCs issued with a specific suite.
+- `checkDataIntegrityProofFormat` checks the proofs of VCs issued with a Data Integrity Suite.
 - `checkDataIntegrityProofVerifyErrors` checks conformant verifiers for support of a Data Integrity Suite.
 
-The suites test normative statements found in the [Verifiable Credential Data Integrity 1.0 specification.](https://w3c.github.io/vc-data-integrity/)
 These functions create mocha suites intended to work with the [mocha-w3c-interop-reporter](https://www.npmjs.com/package/@digitalbazaar/mocha-w3c-interop-reporter)
