Martin, Thank you very much for your quick reply. I have updated mapping files. http://www.geocities.com/murata_makoto/jproCharset.ZIP I find that TR#22 uses the <source>-<name_on_source>-<version> syntax for identifiers. I am wondering if I should change names. Since the Japanese XML Profile has been available for a while, I don't want to change. Cheers, Makoto
