Internet-Draft
     
        (I-D) A draft working document of the {Internet Engineering
        Task Force}, its Areas, and its Working Groups.  As the name
        implies, Internet-Drafts are purely discussion documents with
        no formal status.  They are valid for a maximum of six months
        and may be updated, replaced, or obsoleted by other documents
        at any time.  Very often, an I-D is a precursor to a {Request
        For Comments}.
