SAML/SAMLP vs SAML2/SAMLP2 in assertions

[Jeff McCullough]

Quick question...

I've encountered a vendor, Catertrax, that will only accept SAML/SAMLP for version 1.1 and 2.0 assertions. The Shibboleth IdP sends SAML2/SAMLP2 for SAML 2.0 assertions. The vendor sent me a bunch of links proving their point, but I know you all worked on the spec. What gives? Is there a way in the Shib IdP to specify SAML vs SAML2 assertions for a relying-party?

Thanks,
Jeff
