The namespace URI is

string(namespace::*[name()=substring-before(@xsi:type, ':')])

> xmlns="http://www.aaa.it/consulta/xdmModel"
> xmlns:eur="http://www.aaa.it/europa/xdm"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

>  <document id="kjsdlkj">
>   <category xsi:type="eur:invoice">
>    [...]
>   </category>
>  </document>
>  [...]
> </documents>
