    I'm not looking at material in front of me. I'm tired from travelling.

    I think you oversimplify, and in any case we have UPA and Teuthonista
    both to contend with.

    Sorry, no. There are MILLIONS of citations in Teuthonista in projects
    which have been going on for 150 years. The Germans will have a plain-
    text requirement for this no less than the Uralicists did with UPA.
    That really won't be negotiable, I am sure of it.

    This data must be respected, and there will be explicit discussion
    texts about this published over the next while, in advance of encoding

    No one has made a hard and fast argument yet, Asmus. Kindly do not
