I'm using the Xalan version that comes with the sun jvm. In my case, it is:

$ java -server -version
java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) Server VM (build 14.1-b02, mixed mode)


It is one of the latest java 1.6 versions (the last is 1.6.17), so maybe
is a different bug, I suppose the one you indicated is old enough to be
solved.

Many thanks :) I will try it as soon as you change it.

Oh, I didn't know you split the xsl in several pieces, a good idea if it
gets too long :)
