PSVI for attribute value

[Lara Blatchford]

Hello -

Is there a way to utilize the PSVI data to determine whether the value of the 
xsi:type attribute in the data element is a QName using the DOM API?  It seems 
the value is always returned as XMLCh* .  I need to be able to determine 
whether the "xsd:" in "xsd:string" is legitimately a namespace prefix.


<?xml version="1.0"?>
<xyz xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema";  xmlns="http://xyz.request.org/v1";>
               <abc>333-444444-5</abc>
               <content>
                              <data xsi:type="xsd:string">some text in 
here</data>
               </content>
</xyz>


Thanks!
