EVEN NEVER

       <flags> is one of:
         rw  for configuration data nodes and choice nodes
         ro  for non-configuration data nodes, output parameters to rpcs
             and actions, and notification parameters
         -w  for input parameters to rpcs and actions
         -u  for uses of a grouping
         -x  for rpcs and actions
         -n  for notifications
         mp  for nodes containing a "mount-point" extension statement

         case nodes do not have any <flags>.

My point is that 'data node' is a defined term in RFC 7950 and using
defined terms generally adds clarity.
