Yao Li commented on XMLBEANS-210:
---------------------------------

We are using an open soruce SAML toolkit from Sourceid.org. It use XMLBeans version \
1.0.2. After I upgraded it to use XMLBean 2.1.0, the SAML toolkit stop working on \
Single Sign On. 

After digging around, it appears that the problem with attribute value is QName, and \
new XMLBean does not handle it well (this bug). When checking the SAML reponses \
digital signature, it throws Invalid signature.
