    The comment I received from UTC members on this point was that it was
    not relevant to the argument in favor of Plane 14, because language tags
    in markup carry the same benefits as Plane 14 tags, and language tagging
    belongs in markup.

    After reading the recent posts from Asmus and Ken, it's clear to me that
    the UTC does not want to encourage, or be seen as encouraging, the use
    of Plane 14 tags at all. The protocol I had in mind was plain text,
    which is the entire basis of Unicode and which is not dead, despite what
    some people believe.

    I have given up my campaign to preserve Plane 14 tags and have removed
    the paper from my site. At least it gave me some experience writing a
    position paper for Unicode, and hopefully next time I do one, it will be
    on a topic more in line with the direction of Unicode.
