title: SAML reference documentation?
body: <p>i have been trying to implement SSO using SAML in Java.
  for quite some time i have been referring to blogs by experts and some of the answers on your site.
  I wanted to know if there is a standard reference document which defines all the protocol elements and attributes of SAML request/response and guidance for their use. I have been using it according to my own convenience without following any standards simply exchanging XML messages between web applications.</p>
  
  <p>Thank you.</p>
