 This section defines the "https://iana.org/assignments/http-problem-types#digest-mismatching-value" problem type. A server MAY use this problem type when responding to a request, whose integrity fields include a digest value that does not match the digest value that the server calculated for the request content or representation.
 
-Three problem type extension members are defined: the `algorithm`, `provided-digest`, and `calculated-digest` members. A response using this problem type SHOULD populate all members, with the value of `algorithm` being the algorithm key of the used hashing algorithm, with the value of `provided-digest` being the digest value taken from the request's integrity fields, and the value of `calculated-digest` being the calculated digest. The digest values MUST BE serialized as byte sequences as described in {{Section 4.1.8 of STRUCTURED-FIELDS}}.

 The following example shows a request with the content `{"hello": "woXYZ"}` (plus LF), but the representation digest for `{"hello": "world"}` (plus LF). The subsequent response indicates the mismatching SHA-256 digest values.
