Actually, I thought Scott had added an overloaded String-based way of
getting at subcontexts, and I do see it there in BaseContext.  So you
could try a slightly simpler approach, could even be a (longish) one-liner:


relayState =
resolutionContext.getInboundMessageContext().getSubcontext("org.opensaml.saml.common.messaging.context.SAMLBindingContext").getRelayState();
  

Assuming that works, we will update the Scripted attribute wiki page,
since it still documents the old way of having to get a Class literal. 
The latter is obviously inconvenient in resolver scripts, as well as views.
