Namespace error with XSLTPROC

Hello

 

I am looking at moving my Docbook processing to XSLTPROC. During the 
conversion I see these messages:

------------

Using libxml 20632, libxslt 10123 and libexslt 813
xsltproc was compiled 
against libxml 20632, libxslt 10123 and libexslt 813

namespace error : Namespace prefix fo on bookmark-tree is not

------------

The system complete with no problem, but I did not get any messages like 
this when processing with SAXON 6.5.5 and XSL-1.74.0.

 

 

What causes this?

 

This also does the same thing when using the standard fo/docbook.xsl 
.

 

Is this something that I should be concerned with?

 

 

Regards,
