Added some more trace: 

[3/1/10 13:26:34:209 EST] 0000001d SystemOut     O   Starting to 
unmarshall DOM element

[3/1/10 13:26:34:209 EST] 0000001d SystemOut     O   Node type: 2

So it is trying to unmarshall the "ID" attribute of the Assertion Element. 
Clearly we can print out the NodeName of the attribute but localname is null. 
For that reason XMLHelper.getNodeQName(attribute)) throws the error. 

Per the documentation of getLocalNamepublic String getLocalName()
Returns the local part of the qualified name of this node. 
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes 
created with a DOM Level 1  method, such as createElement from the Document 
interface, this is always null. 
Since:
DOM Level 2

Here is my assertion element for reference.

<saml2:Assertion xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion"

How can I ensure that the attribute has a localname??? 



thanks
Sid
