5. Mandatory Headers
An article MUST have one, and only one, of each of the following
headers: Date, From, Message-ID, Subject, Newsgroups, Path.
Note also that there are situations, discussed in the relevant parts
of section 6, where References, Sender, or Approved headers are
mandatory. In control messages, specific values are required for
certain headers.
For the overall syntax of headers, see section 4.1. In the
discussions of the individual headers, the content of each is
specified using the syntax notation. The convention used is that the
content of, for example, the Subject header is defined as .
A proto-article (see 8.2.1) may lack some of these mandatory headers,
but they MUST then be supplied by the injecting agent.
