DOCBOOK-APPS: xmlns problem with xhtml

[Bruno VERNAY <Bruno dot VERNAY at Proval dot fr>]

Title: xmlns problem with xhtml

I use
        - SAXON 6.5.1  The complete version with win2k :
                "C:\j2sdk1.4.0\bin\java -jar saxon.jar ..."

        - Docbook XSL 1.50.0 (same with 1.49)

I have a problem with link in XHTML (single or chunked) :
        I get this <a xmlns:.0="" .0:href=""http://www.w3.org/" .0:target="_top" ...
        instead of <a href=""http://www.w3.org/" target="_top" ...

For now, I replace all the ".0:" by "" in all the files. Is there an other solution ?

Thanks
