    OK, this time you are right and I am wrong; although your definition
    does not include all canonically equivalent orderings of your "starter
    sequence" because it excludes ones in which a combining character in
    class b is ordered between two of class a, a not equal to b.

    This time you did, by sending to the main list your reply to my posting
    to the Hebrew list.

    For once only I am sending this to both lists, as my incorrect statement
    to one list was cross-posted to the other one and so needs to be
    corrected on both lists.

    In future I will try to keep postings about general issues on the
    general list and postings going into Hebrew specifics on the Hebrew
    list. I hope those who reply to such postings will reflect my intentions
    and not cross-post what I have written without permission (though I have
    no problem with short quotes from one list on the other one).
