DOCBOOK-APPS: Saxon bug?

[dbook@centrum.cz]

Hi,
can anybody explain me what's wrong? I'm writing XSL style sheet
for DocBook DTD document. Output files should be XHTML. 

The question is why I always get line like:

<span xmlns:.0="" .0:class="emphasis"><em>something</em></span>

when the source is <emphasis>something</emphasis>.

The output file is not well-formed because of .0, the same case 
come on with element <xref>.

I was trying various vrsions of SAXON, but it's same.
Is only way rewriting templates in my XSL, or I haven't something 
set?

Jiri
