title: SCIM 2.0 - How to provision entitlements, and how to link them to groups
body: <p>I've read RFC7644, and RFC7643, and have a few questions.</p>
  
  <p>First: how do I provision entitlements? I see there's a default methodology for provisioning groups and users. That includes a pretty straightforward mechanism for provisioning users' membership in groups, entitlements they have, and roles they have.</p>
  
  <p>I also see that there's a mechanism for creating a group with members in it during provisioning.</p>
  
  <p>What I don't see is a built-in mechanism for creating a group, and linking entitlements to it (or creating entitlements that are then linked to groups).</p>
  
  <p>Do I need to build a custom schema extension for groups? Do I need to build a custom schema for entitlements?</p>
  
  <p>My second question is: how exactly DO I create custom extensions and schemas? The RFCs are pretty vague about how you might do that while being compliant with their standard.</p>
