Section Appendix B says:

    +-----------------+---------+------+--------+-----+--------+------+
    | *  Dest Unreach | SHLD-25 |  X   |        |     |        |      |
    |    (0,1,5) =>   |         |      |        |     |        |      |
    |    inform ALP   |         |      |        |     |        |      |
    +-----------------+---------+------+--------+-----+--------+------+

It should say:

    +-----------------+---------+------+--------+-----+--------+------+
    | *  Dest Unreach | SHLD-25 |      |   X    |     |        |      |
    |    (0,1,5) =>   |         |      |        |     |        |      |
    |    inform ALP   |         |      |        |     |        |      |
    +-----------------+---------+------+--------+-----+--------+------+

Notes:

This requirement has an X in the "MUST" column, but the X should be in the "SHOULD" column.

The relevant text for this requirement is "a TCP implementation ... SHOULD make the information available to the application (SHLD-25)."
