OpenSAML user discussion

The Shibboleth open source project provides an example, I think.  See
class XMLKeyDescriptor defined in public class XMLMetadataProvider:

http://svn.middleware.georgetown.edu/view/tags/Rel_1_3_FINAL_C/src/edu/internet2/middleware/shibboleth/metadata/provider/XMLMetadataProvider.java?root=java-idp&view=log

and its use in classes BasicTrust and ShibbolethTrust:

http://svn.middleware.georgetown.edu/view/tags/Rel_1_3_FINAL_C/src/edu/internet2/middleware/shibboleth/common/provider/BasicTrust.java?root=java-idp&view=log
http://svn.middleware.georgetown.edu/view/tags/Rel_1_3_FINAL_C/src/edu/internet2/middleware/shibboleth/common/provider/ShibbolethTrust.java?root=java-idp&view=log

Hope this helps,
Tom
