I have reworked the ENRP paragraph and also created an additional figure to 
show the role of ENRP:

<t>It is envisioned that ENRP servers provide a fully distributed and
fault-tolerant registry service. They use
<xref target="I-D.ietf-rserpool-enrp">ENRP</xref> to
maintain synchronization of data concerning the pool handle mapping space.
For PUs and PEs, the ENRP servers are functionally equal. Due to the
synchronization provided by ENRP, they can contact an arbitrary one for
registration/deregistration (PE) or PH resolution (PU).  An illustration
containing 3 ENRP servers is provided in
<xref target="examplefig-enrp"/> below:</t>
