Bring xml in better "shape"

[321los]

Hi,
I want to offer my visitors the possibility to get the content they are reading as a XML File.
Sadly when using the xml serializer, the output xml does not look very appealing. See yourself:

Can I somehow improve that?

2nd:
as you can see, the root element (document) has the sql namespace. Why is it displayed there? I mean, I have it in my transforming xsl file, like that:
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform "
xmlns:sql="http://apache.org/cocoon/SQL/2.0">

but why is it displayed in the final xml?

Thanks
Marco
