FTS Thesaurus Diacritics

Has anyone played with the <diacritics> or <diacritics_sensitive> tag in the
thesaurus for FTS? If so, have you actually gotten it to affect your
results? It doesn't matter what I change it to, in testing it appears to be
over-ruled by the FT Catalog accent sensitivity setting.

After a little further review, it appears the <diacritics> and
<diacritics_sensitive> tags are not even included in the schema definition
for the thesaurus files. There is an optional "weight" attribute assigned
to the <sub> elements, however. Is this documented anywhere?
Thanks.
