DocBook, XALAN, titlepage.xsl template

[Andrea Mattioli <aldaris@jumpy.it>]

Hi,
applying "docbook-xsl-1.69.1\template\titlepage.xsl" to a new 
"titlepage.templates.xml" file with XALAN, the resulting XSL doesn't 
cointain the namespace exsl:

xmlns:exsl="http://xml.apache.org/xalan";

and I get the javax.xml.transform.TransformerException.

- Is it a XALAN or DocBook problem ?
	If it is a XALAN problem what I can say to report this bug and 
explain it in a precise way?
- What can I do to add that namespace prefix automatically ?

Thank you,
Andrea.
