+Implementations MUST treat the base context value, located at
+`https://www.w3.org/ns/did/v1.1`, as already retrieved;
+the following value is the hexadecimal encoded SHA2-256 digest value of the base
+context file: <code><span class="vc-hash"
+data-hash-url="https://www.w3.org/ns/did-vocab/v1.1rc1.jsonld"
+data-hash-format="openssl dgst -sha256" /></code>. It is possible to confirm
+the cryptographic digest above by running the following command from a modern
+Unix command line interface:
+`curl -s https://www.w3.org/ns/did/v1.1 | openssl dgst -sha256`.

+Implementers are warned that other data that is referenced from within a
+[=DID document=], such as resources that are linked to via URLs, are not
+cryptographically protected by default. It is considered a best practice to
+ensure that the same sorts of protections are provided for any URL that is
+critical to the security of the [=DID document=] through the use of
+permanently cached files and/or cryptographic hashes. Ultimately, knowing the
+cryptographic digest of any linked external content enables an application to
+confirm that the content is the same as what the [=DID controller=] intended.

+        <p class="note" title="See errata if hash value changes are detected">
+It is extremely unlikely that the files that have associated cryptographic hash
+values in this specification will change. However, if critical errata are
+found in the specification and corrections are required to ensure
+ecosystem stability, the cryptographic hash values might change. As such, the
+HTTP cache times for the files are not set to infinity and implementers are
+advised to check for errata if a change is detected in a cryptographic hash
+value.
