      *   are standards track documents, and that not all    *
      *   standards track documents reach the level of       *
      *   Internet Standard. In the same way, not all RFCs   *

2.2  Internet-Drafts

   During the development of a specification, draft versions of the
   document are made available for informal review and comment by
   placing them in the IETF's "Internet-Drafts" directory, which is
   replicated on a number of Internet hosts.  This makes an evolving
   working document readily available to a wide audience, facilitating
   the process of review and revision.

   An Internet-Draft that is published as an RFC, or that has remained
   unchanged in the Internet-Drafts directory for more than six months
   without being recommended by the IESG for publication as an RFC, is
   simply removed from the Internet-Drafts directory.  At any time, an
   Internet-Draft may be replaced by a more recent version of the same
   specification, restarting the six-month timeout period.

   An Internet-Draft is NOT a means of "publishing" a specification;
   specifications are published through the RFC mechanism described in
   the previous section.  Internet-Drafts have no formal status, and are
   subject to change or removal at any time.

      *   be referenced by any paper, report, or Request-    *
      *   for-Proposal, nor should a vendor claim compliance *

RFC 2026               Internet Standards Process           October 1996


   Note: It is acceptable to reference a standards-track specification
   that may reasonably be expected to be published as an RFC using the
   phrase "Work in Progress"  without referencing an Internet-Draft.
   This may also be done in a standards track document itself  as long
   as the specification in which the reference is made would stand as a
   complete and understandable document with or without the reference to
   the "Work in Progress".

3.  INTERNET STANDARD SPECIFICATIONS

   Specifications subject to the Internet Standards Process fall into
   one of two categories:  Technical Specification (TS) and
   Applicability Statement (AS).

3.1  Technical Specification (TS)

   A Technical Specification is any description of a protocol, service,
   procedure, convention, or format.  It may completely describe all of
   the relevant aspects of its subject, or it may leave one or more
   parameters or options unspecified.  A TS may be completely self-
   contained, or it may incorporate material from other specifications
   by reference to other documents (which might or might not be Internet
   Standards).

   A TS shall include a statement of its scope and the general intent
   for its use (domain of applicability).  Thus, a TS that is inherently
   specific to a particular context shall contain a statement to that
   effect.  However, a TS does not specify requirements for its use
   within the Internet;  these requirements, which depend on the
   particular context in which the TS is incorporated by different
   system configurations, are defined by an Applicability Statement.

3.2  Applicability Statement (AS)

   An Applicability Statement specifies how, and under what
   circumstances, one or more TSs may be applied to support a particular
   Internet capability.  An AS may specify uses for TSs that are not
   Internet Standards, as discussed in Section 7.

   An AS identifies the relevant TSs and the specific way in which they
   are to be combined, and may also specify particular values or ranges
   of TS parameters or subfunctions of a TS protocol that must be
   implemented.  An AS also specifies the circumstances in which the use
   of a particular TS is required, recommended, or elective (see section
   3.3).
