I've submitted an updated version of the loop-free alternates draft.
The major changes are as follows:
        1) Section on local hold-down which is a SHOULD
2) Discussion of downstream paths & loop-free alternates, with looping scenario shown for link-protecting alternates in the event of node
        3) Clarified the behavior for broadcast links
        4) Cleaned up the text a lot and more clearly specified the behavior.

Please send any comments to the list.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Routing Area Working Group Working Group of the IETF.
        Title           : Basic Specification for IP Fast-Reroute:
                          Loop-free Alternates
        Author(s)       : A. Atlas
        Filename        : draft-ietf-rtgwg-ipfrr-spec-base-01.txt
        Pages           : 18
        Date            : 2004-10-4

This document defines an architecture and selection process for
   providing local protection for IP unicast and/or LDP traffic in the
   event of a single link or node failure until the router has
   converged.  When computing the primary next-hop for a prefix, a
   router S also determines an alternate next-hop which can be used if
   the primary next-hop fails.  The alternate next-hop is said to be a
   loop-free alternate, which goes to a neighbor whose shortest path to
   the prefix does not go back through the router S.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
