xmlns empty string

Hi,

I have the following schema instance and the xmlns on contact nodes are empty strings.
I use xmlbeans for databinding in Axis2. and would like to not use any ns on contact.

How do I manupulate xmlns in my schema (or using xbean api) for contact node to get rid of xmlns="" ?

<Contacts xmlns="www.example.com">
     <Contact xmlns="" id="3" name="abc2" />
     <Contact xmlns="" id="4" name="abc3" />
     <Contact xmlns="" id="5" name="abc4" />
     ....
</Contacts>

Thanks very much
