OpenSAML user discussion

I wanted to check if I misunderstood part of thread on this list, it sounded 
like one should not use OpenSAML to sign Response objects if one is using 
SAML 1.0.  Rather, it sounds like OpenSAML should be set to use SAML 1.1 if 
one is creating and signing Responses.  So I wanted to check, if that right?

One more clarifying question, is it safe to say that even if OpenSAML should 
only use SAML 1.1 to *sign* Responses, it nevertheless is fine for consuming 
and *verifying* SAML 1.0 Responses?

(I did skim through past threads, but couldn't quite find a definitive 
answer.  I apologize in advance if I missed something)
