RFC 7489, "Domain-based Message Authentication, Reporting, and Conformance (DMARC)", March 2015Source of RFC: INDEPENDENT

Section 220.127.116.11 says:
The aggregate data MUST be an XML file that SHOULD be subjected to GZIP compression.
It should say:
The aggregate data MUST be an XML file that SHOULD be subjected to GZIP compression (described in [RFC1952]).
The term "GZIP compression" is not defined in the text. To clarify, maintain compatibility with future (potentially incompatible) gzip versions, and to bring the document in line with other RFCs (e.g. 3712, 6713, 6968), a reference to RFC 1952 ("GZIP file format specification version 4.3") should be added.
This is assuming RFC 1952 was the author's intent.
