First, I really don't understand your error message - it says there was
trouble on line 234, but your posted stylesheet has less than 20 lines.

Second, when I try your posted stylesheet with the current release of
xsltproc, it seems to work with no problem:

wbrack bbrack work $ xsltproc --version
Using libxml 20615, libxslt 10109 and libexslt 807
xsltproc was compiled against libxml 20615, libxslt 10109 and libexslt 807
libxslt 10109 was compiled against libxml 20615
libexslt 807 was compiled against libxml 20615
wbrack bbrack work $ xsltproc bug.xsl bug.xsl
<?xml version="1.0"?>
Test succeeded

Could you please be more clear on this report?

Thanks,
Bill
