Section 3.2 says:

 Example 5:

      C: c101 STORE 1 (UNCHANGEDSINCE 12121230045) -FLAGS.SILENT
         (\Deleted)
      S: * OK [HIGHESTMODSEQ 12111230047]
      S: * 50 FETCH (MODSEQ (12111230048))
      S: c101 OK Store (conditional) completed

It should say:

Example 5:

      C: c101 STORE 50 (UNCHANGEDSINCE 12121230045) -FLAGS.SILENT
         (\Deleted)
      S: * OK [HIGHESTMODSEQ 12111230047]
      S: * 50 FETCH (MODSEQ (12111230048))
      S: c101 OK Store (conditional) completed

Notes:

Since successful conditional stores MUST return the FETCH (MODSEQ) data for every message that was changed, the untagged FETCH response in this example should refer to the same message as the STORE command. To avoid any suggestion that 1 might be a special case, I have made the correction to use 50 in both contexts.

Section 3.2 says:

      However, if the mod-sequence of any metadata item of the message
      is greater than the specified UNCHANGEDSINCE value, then the
      requested operation MUST NOT be performed.  In this case, the
      mod-sequence attribute of the message is not updated, and the
      message number (or unique identifier in the case of the UID STORE
      command) is added to the list of messages that failed the
      UNCHANGESINCE test.

      When the server finished performing the operation on all the
      messages in the message set, it checks for a non-empty list of
      messages that failed the UNCHANGESINCE test.  If this list is
      non-empty, the server MUST return in the tagged response a
      MODIFIED response code.  The MODIFIED response code includes the
      message set (for STORE) or set of UIDs (for UID STORE) of all
      messages that failed the UNCHANGESINCE test.

   Example 3:

      All messages pass the UNCHANGESINCE test.

      C: a103 UID STORE 6,4,8 (UNCHANGEDSINCE 12121230045)
          +FLAGS.SILENT (\Deleted)
      S: * 1 FETCH (UID 4 MODSEQ (12121231000))
      S: * 2 FETCH (UID 6 MODSEQ (12121230852))
      S: * 4 FETCH (UID 8 MODSEQ (12121130956))
      S: a103 OK Conditional Store completed

This erratum changes "UNCHANGESINCE" to "UNCHANGEDSINCE" in four places.

Section 4. says:

   resp-text-code      =/ "HIGHESTMODSEQ" SP mod-sequence-value /
                          "NOMODSEQ" /
                          "MODIFIED" SP set

It should say:

   resp-text-code      =/ "HIGHESTMODSEQ" SP mod-sequence-value /
                          "NOMODSEQ" /
                          "MODIFIED" SP sequence-set

Notes:

RFC 1730 and RFC 2060 mentioned "set". It's been changed to sequence-set in RFC 3501.
Therefore, I think the same name should be applied in RFC 4551.
