Section 16.2 says:

   TC messages MAY be generated in response to a change in the
   information that they are to advertise, indicated by a change in the
   ANSN in the Neighbor Information Base.  In this case, a router MAY
   send a complete TC message and, if so, MAY restart its TC message
   schedule.  Alternatively, a router MAY send an incomplete TC message
   with at least the newly advertised network addresses (i.e., not
   previously, but now, an N_orig_addr or in an N_neighbor_addr_list in
   a Neighbor Tuple with N_advertised = true or an AL_net_addr) in its
   Address Blocks, with associated Address Block TLV(s).  Note that a
   router cannot report removal of advertised content using an
   incomplete TC message.

It should say:

   TC messages MAY be generated in response to a change in the
   information that they are to advertise, indicated by a change in the
   ANSN in the Neighbor Information Base.  In this case, a router MAY
   send a complete TC message and, if so, MAY restart its TC message
   schedule.  Alternatively, a router MAY send an incomplete TC message
   with at least the newly advertised network addresses (i.e., not
   previously, but now, an N_orig_addr or an N_neighbor_addr_list in
   a Neighbor Tuple with N_advertised = true or an AL_net_addr) in its
   Address Blocks, with associated Address Block TLV(s).  Note that a
   router cannot report removal of advertised content using an
   incomplete TC message.

Notes:

Unnecessary preposition "in"
--VERIFIER NOTES--
From Christopher Dearlove (author):

The "in" distinguishes the cases of N_orig_addr and an N_neighbor_addr_list. The former is a single address, the latter is a list of addresses. Therefore one looks for the address as the former, or in (the word that should not be deleted) the latter.

This erratum must be rejected.
