RFC 8461, "SMTP MTA Strict Transport Security (MTA-STS)", September 2018

Section 3.2 says:

CRLF-separated key/value pairs

It should say:

LF- or CRLF-separated key/value pairs

Notes:

Rationale:

1. The definition of 'sts-policy-term' in the grammar explicitly allows use of either CRLF or bare LF.

2. On page 8, one of the example says "<CRLF>" explicitly at the end of the first line, while the second line of that example and all lines of the other example have neither "<CRLF>" nor "<LF>" appended to them. That makes it ambiguous whether those lines are terminated by LF or by CRLF.
