Noel, the Loc-AFI is describe during the 'Locator' description is made:

   Locator:  an IPv4 or IPv6 address (as encoded by the 'Loc-AFI'  
field)
      assigned to an ETR or router acting as a proxy replier for the
      EID-prefix.  Note that the destination RLOC address MAY be an
      anycast address.  A source RLOC can be an anycast address as  
well.
      The source or destination RLOC MUST NOT be the broadcast address
      (255.255.255.255 or any subnet broadcast address known to the
      router), and MUST NOT be a link-local multicast address.  The
      source RLOC MUST NOT be a multicast address.  The destination  
RLOC
      SHOULD be a multicast address if it is being mapped from a
      multicast destination EID.
