I have updated the abstract and introduction to (hopefully) be more clear.

Abstract

The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest
Algorithm Values" defines values for digest algorithms used by
Instance Digests in HTTP. Instance Digests in HTTP provide a digest,
also known as a checksum or hash, of an entire representation of the
current state of a resource. This draft adds new values to the
registry and updates previous values.

Introduction

The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest
Algorithm Values" defines values for digest algorithms used by
Instance Digests in HTTP.

Note: This is unrelated to HTTP Digest Authentication. Instance
Digests in HTTP provide a digest, also known as a checksum or hash, of
an entire representation of the current state of a resource.
