Thank you for vour investigation.

The difference is, that in „geißeln“ the hyphenation is in front of the 
ß, in „wußte“ behind it. Those before ß XeTeX looses always, the others 
only sometimes.

With babel it works fine, when you give them the marks with 
\hyphenation{}. I don't understand this difference, but I want XeTeX to 
find the hyphenation points from the patterns, as all the others.
