Thanks a lot! The version with the "lang" parameter is working.

When I need specific rules that differ from the standard Java "de" locale, I
would have to set up my own RuleBasedCollator class. I found samples in the
Java tutorials how to write down the rules but I'm not well versed enough in
Java to wrap that properly up so that it works with Saxon. May I bother you
with asking for a working sample file with the right Java code in it if you
happen to have that readily available.

Thanks for taking your time to assist me!

Wolfgang

This will vary from one product to another, but the facilities in Saxon are
defined at

http://www.saxonica.com/documentation/extensibility/collation.html

You should be able to get a collation suitable for German simply by using
lang="de" on xsl:sort, though it you need to use it for other operations
such as < and > then you will need to use a collation URI, which in Saxon is

http://saxon.sf.net/collation?lang=de

If you want to set up your own Java RuleBasedCollator you can; if the
relevant class is BasicGerman and it's on the classpath then you can use

http://saxon.sf.net/collation?class=BasicGerman

If you don't want to use Saxon-specific URIs, then you can implement your
own CollationURIResolver.

Saxon-specific questions are best asked on the saxon-help list or forum at
SourceForge.net
