registers a media type and content encoding to be used when
transporting zstd-compressed content via Multipurpose Internet Mail
Extensions (MIME).
Despite use of the word "standard" as part of its name, readers are
advised that this document is not an Internet Standards Track

RFC Editor Note
RFC Editor Note
Per feedback from the IANA reviewer for the suffix registration, please amend the first paragraph of the Abstract to read as follows:
Zstandard, or "zstd" (pronounced "zee standard"), is a data
compression mechanism. This document describes the mechanism and
registers a media type and content encoding to be used when
transporting zstd-compressed content. It also registers a
corresponding media type, content encoding, and structured syntax suffix.
Also update the last paragraph in Section 1 to read as follows:
This document describes the Zstandard format. Also, to enable the
transport of a data object compressed with Zstandard, this document
registers a media type, content encoding, and structured syntax suffix
that can be used to identify such content when it is used in a payload.
