docbook-xsl-1.60.0 vs. german hyphenation

Hi,

I'm having trouble producing PDF output from docbook-xsl-1.61.0:

java  -classpath
$CLASSPATH:/usr/share/java/saxon.jar:/usr/share/java/saxon-fop.jar:/KM/usr/ziegler/DocBook/docbook-xsl-1.61.0/extensions/saxon644.jar 

com.icl.saxon.StyleSheet  -o pdf/LEDATutorium.fo LEDATutorium.xml
XSLT/FOPsheet.xsl

Making portrait pages on A4 paper (210mmx297mm)
No "de" localization of "hyphenation-character" exists; using "en".

No "de" localization of "hyphenation-remain-character-count" exists;
using "en".No "de" localization of "hyphenation-character" exists; using
"en".
No "de" localization of "hyphenation-push-character-count" exists; using
"en".
No "de" localization of "hyphenation-remain-character-count" exists;
using "en".No "de" localization of "hyphenation-character" exists; using
"en".
No "de" localization of "hyphenation-push-character-count" exists; using
"en".
.

.

And in the resulting PDF, there is really no hyphenation any more.
