Hello George

First of all thanks for your answer.
I started now to use XSLT 2.0 and the code completion is working fine now.

I removed the xsi namespace-prefix and now the namespace with prefix do
not appear anymore in the output file. The only problem I still have, is
that in the out docbook file there is already. My intention is to create a
docbook file, which has the DTD part without the default namespace in the
root element.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
"http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd">
<book xmlns="http://www.oasis-open.org/docbook/xmlschema/4.1.2" lang="en">
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
