Example 4       <<    >>   index    

It is a common practice to declare all namespaces within the root element.


     <lower:aaa xmlns:lower = "http://zvon.org/lowercase" xmlns:upper = "http://zvon.org/uppercase"
          xmlns:xnumber = "http://zvon.org/xnumber" >
          <lower:bbb >
               <lower:ccc />
          </lower:bbb>
          <upper:BBB >
               <upper:CCC />
          </upper:BBB>
          <xnumber:x111 >
               <xnumber:x222 />
          </xnumber:x111>
     </lower:aaa>
