Generate custom XSL templates

["Luca Giandoso" <luca.giandoso@gmail.com>]

I'm using docbook distribution 1.71.0.
I would like to customize th title page so I've followed:
http://www.sagehill.net/docbookxsl/TitlePageNewElems.html

But when I look at the xsl as result it contains :
<?xml version="1.0"?>
and a lot of spaces

To be sure I've tried with the files shipped with the docbook xsl distribution.
Here the command I've used:

xsltproc -v -output mytitlepage.xsl
/usr/share/xml/docbook/stylesheet/nwalsh/fo/titlepage.xsl
/usr/share/xml/docbook/stylesheet/nwalsh/fo/titlepage.templates.xml

using the -v option I get lots of

xsltProcessOneNode: no template found for *

where * stands for titlepage, titlepage-content, etc...

I think I'm missing something but I don't know.
Thank you in advance.
