[4suite] Question on namespace and amara

[Werner F. Bruhin]

I am trying to do some query to a wine related web site using xml which 
needs the following in the xml string.

<?xml version="1.0" encoding="utf-8"?>
<query xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://www.vinoxml.org/XMLschema">
    <querycreator>
...etc...

I create the doc with:
doc = binderytools.bind_string(doc_header)

doc_header contains the above plus whatever else is needed,  but when I 
do doc.xml() the namespace (is this the right name) stuff is dropped.

Can anyone point me in the right direction on how to go about this with 
amara.

Thanks
Werner

P.S.
I use version '1.2.0.1'
