Section 25.1 says:
Errata ID: 316 digest-uri-value = request-uri ; Equal to request-uri as specified by HTTP/1.1
It should say:
digest-uri-value = rquest-uri ; Equal to request-uri as specified by HTTP/1.1
Rule names are case-insensitive.
Request-URI has been defined already.
An original definition is correct.
Alternatively, it may refer to request-target as specified by RFC 7230.
