Your problem seems to be related to this Xalan bug:
http://issues.apache.org/jira/browse/XALANJ-2223. 

I don't know why you get that exception. Xalan works for me if I change
common/pi.xsl so that function-available('exsl:nodeSet') is used. The
command line is this (JDK 1.5.0):

java -cp
c:/Java/xalan-j_2_7_0/xercesImpl.jar;c:/Java/xalan-j_2_7_0/xml-apis.jar;C:/J
ava/xalan-j_2_7_0/xalan.jar org.apache.xalan.xslt.Process -OUT test.html -IN
xml/test.xml -XSL C:/doctypes/docbook/xsl/html/docbook.xsl

And test.xml looks like this:

<section>
  <title>TEST</title>
  <para>
    Generated: <?dbtimestamp format="Y-m-d H:M:S"?>
  </para>
</section>
