1.6  Structure of This Document

   This document uses a cite by reference methodology, rather than
   repeating the contents of other standards, which could otherwise
   result in subtle differences and interoperability challenges.
   Although this document is as a result rather short, it requires
   complete understanding and implementation of the normative references
   to be compliant.

   Section 2 defines the format of news articles.  Section 3 details the
   headers necessary to make an article suitable for the netnews
   environment.

-1.3. Structure of this document
+1.6  Structure of This Document
 
-   This document is divided into several sections.
-
-   This section, section 1, is a short introduction to the document.
-
-   Section 2 lays out the general description of a message and its
-   constituent parts.  This is an overview to help the reader understand
-   some of the general principles used in the later portions of this
-   document.  Any examples in this section MUST NOT be taken as
-   specification of the formal syntax of any part of a message.
-
-   Section 3 specifies formal ABNF rules for the structure of each part
-   of a message (the syntax) and describes the relationship between
-   those parts and their meaning in the context of a message (the
-   semantics).  That is, it describes the actual rules for the structure
-   of each part of a message (the syntax) as well as a description of
-   the parts and instructions on how they ought to be interpreted (the
-   semantics).  This includes analysis of the syntax and semantics of
-   subparts of messages that have specific structure.  The syntax
-   included in section 3 represents messages as they MUST be created.
-   There are also notes in section 3 to indicate if any of the options
-   specified in the syntax SHOULD be used over any of the others.
-
-   Both sections 2 and 3 describe messages that are legal to generate
-   for purposes of this standard.
-
-   Section 4 of this document specifies an "obsolete" syntax.  There are
-   references in section 3 to these obsolete syntactic elements.  The
-   rules of the obsolete syntax are elements that have appeared in
-   earlier revisions of this standard or have previously been widely
-   used in Internet messages.  As such, these elements MUST be
-   interpreted by parsers of messages in order to be conformant to this
-   standard.  However, since items in this syntax have been determined
-   to be non-interoperable or to cause significant problems for
-   recipients of messages, they MUST NOT be generated by creators of
-   conformant messages.
-
-   Section 5 details security considerations to take into account when
-   implementing this standard.
-
-   Section 6 is a bibliography of references in this document.
-
-   Section 7 contains the editor's address.
-
-   Section 8 contains acknowledgements.
-
-   Appendix A lists examples of different sorts of messages.  These
-   examples are not exhaustive of the types of messages that appear on
-   the Internet, but give a broad overview of certain syntactic forms.
-
-   Appendix B lists the differences between this standard and earlier
-   standards for Internet messages.
-
-   Appendix C has copyright and intellectual property notices.
