problem with docbook-xsl-1.72.0

Hi,

I'm trying to switch from 1.69.1 to 1.72.0.
When using 1.72.0 with xalan-1.2.7.0 we get the error: (It's a german WindowsXP...)

xalan.bat -PARAM base.dir html/ -PARAM chunk.first.sections 1 -PARAM chunk.section.depth 2 -PARAM use.id.as.filename 1 -ENTITYRESOLVER org.apache.xml.resolver.tools.CatalogResolver -URIRESOLVER org.apache.xml.resolver.tools.CatalogResolver -in user_manual.xml -xsl "%DOCBOOK_XSL_HOME%/xhtml/chunk.xsl"

What is the problem with the $language value?
I tried to set various language param values but couldn't solve the problem.

Any help?
