Ok.

This is probably just fine, but note that in your example you did:

             <users>
               <user>
                 <name>fred</name>
                 <type/>
                 <full-name/>
               </user>
               <role/>                            <!-- user's sibling-->
             </users>

Which would correspond to this:

  container users {
      list user { ... }
      leaf role { ... }
  }

so the role - in your example - isn't a property of the user, but a
global property for all users.


The reasoning applies even if we do:

  container users {
      list user {
          ...
          leaf role { ... }
      }
  }
