    the use of diaeresis is perfectly valid for words in fields that have a
    language ID 'German'.

    First off, there have to be corresponding entries in the sorting tables
    used for such data, to make that distinction have the correct effect. Since
    the sorting tables would not support anything ohter than <BASE, CGJ,
    DIAERESIS> there's no reason to introduce other sequences into the data.

    Secondly, the dieresis is used to indicate that two vowels are pronounced
    separately. I haven't seen a case where the vowels would already be accented.

    Finally, one of the additional reasons that the phonetic sorting is
    relevant in this instance, other than that the pronunciations are in fact
    different, is that the use of diaeresis is not mandatory to the same degree
    as for umlauts. You can find Kapernaum spelled with and without it, but if
    you spell Hauser with it, it's the plural of Haus, without it it's a name.
    Personal names however, sometimes are spelled with vowel + e (Moeller).

    By sorting dieresis as a secondary difference, related terms do sort
    together, and names sort near their variant spellings. The suggested
    approach solves the problem at hand for those data where somebody took the
    trouble to decide (on input) which was which, so that huge catalogs of
    subject keywords or authors come out correctly.

    Note, the bulk of all possible data in German won't make that distinction,
    and won't be used on systems that support the special sorting method.
