That's a good question. You're not the first to ask for a lightweight
SAML protocol binding.

That's an interesting if not curious variation on SAML Web Browser
SSO. By "attribute query" I assume you do NOT mean SAML
AttributeQuery since I can't imagine what a browser user might do with
one.

The HTTP bindings in SAML are not general purpose HTTP bindings. They
were written with SAML Web Browser SSO in mind. If you want a
lightweight HTTP binding, you might want to look at OAuth.
