title: What is a XACML profile?
body: <p>I'm new to XACML (the eXtensible Access Control Markup Language), and I'm a bit confused.
  I don't get what a profile is. For example the RBAC or SAML profiles.</p>
  
  <p>What's the difference among them? Isn't the structure and elements always the same?</p>
  
  <p>Thank you for you help</p>
