Parsing a SAML Response object using OpenSSO

I'm trying to do something that seems rather simple but am getting unexpected results. I'm using the OpenSSO library to parse a SAML 1.1 Response, provided as a String of开发者_开发百科 XML. Since I have a sample Response from the client I've set up a simple unit test just to verify that I can parse it but get the following errors:

com.sun.identity.saml.protocol.Response.parseXML(<xml string>)

...

AuthenticationStatement:Wrong element Subjectincluded.

There are Subject nodes in both the AuthenticationStatement and the AttributeStatement.

I simply want to parse the provided XML, check the status and pull out the NameIdentifier. This is entirely new to me so please excuse the ignorance.

I cannot find anything about the "Subjectincluded" element in SAML specs. Please review your XML. If this is some kind of an extension to SAML, I think it will be safe to simply remove that element.
