4.3.2. Body Conventions
A body is by default an uninterpreted sequence of octets for most of
the purposes of this standard. However, a MIME Content-Type-header
may impose some structure or intended interpretation upon it, and may
also specify the character set in accordance with which the octets
are to be interpreted.
The following conventions for quotations, attributions and
signatures, although not mandated by this standard, describe widely
used practices. They are documented here in order to establish their
correct usage, and the use of the words "MUST", "SHOULD", etc. is to
be understood in that context.
It is conventional for followup agents to enable the incorporation of
the followed-up article (the "precursor") as a quotation. This SHOULD
be done by prefacing each line of the quoted text (even if it is
empty) with the character ">" (or perhaps with "> " in the case of a
previously unquoted line). This will result in multiple levels of ">"
when quoted content itself contains quoted content, and it will also
facilitate the automatic analysis of articles.
NOTE: Posters should edit quoted context to trim it down to the
minimum necessary. However, followup agents Ought Not to attempt
to enforce this beyond issuing a warning (past attempts to do so
have been found to be notably counter-productive).
The followup agent SHOULD also precede the quoted content by an
"attribution line" (however, readers are warned not to assume that
they are accurate, especially within multiply nested quotations). The
following convention for such lines is intended to facilitate their
automatic recognition and processing by sophisticated reading agents.
The attribution SHOULD contain the name and/or the email address of
the precursor's poster, as in

The attribution MAY contain also a single newsgroup-name (the one
from which the followup is being made), the precursor's Message-ID
and/or the precursor's Date and Time. Any of these that are present,
SHOULD precede the name and/or email address. However, the inclusion
or not of such fields Ought always to be under the control of the
poster.
To enable this line, and the Message-ID and the email address within
it, to be recognized (for example to enable suitable reading agents
to retrieve the precursor or email its poster by clicking on them),
the following conventions SHOULD be observed:
o The precursor's Message-ID SHOULD be enclosed within <...> or
<news:...>
o The precursor's poster's email address SHOULD be enclosed within
<...>
o The various fields may be separated by arbitrary text and they
may be folded in the same way as headers, but attributions SHOULD
always be terminated by a ":" followed by CRLF.

A "personal signature" is a short closing text automatically added to
the end of articles by posting agents, identifying the poster and
giving his network addresses, etc. Whenever a poster or posting agent
appends such a signature to an article, it MUST be preceded with a
delimiter line containing (only) two hyphens (US-ASCII 45) followed
by one SP (US-ASCII 32). The signature is considered to extend from
the last occurrence of that delimiter up to the end of the article
(or up to the end of the part in the case of a multipart MIME body).
Followup agents, when incorporating quoted text from a precursor,
Ought Not to include the signature in the quotation. Posting agents
Ought to discourage (at least with a warning) signatures of excessive
length (4 lines is a commonly accepted limit).
