Section 3.2.3 says:

<request>::= <RP>
                    <segment-computation> | <path-key-expansion>

       where:
          <segment-computation> ::= <END-POINTS>
                                    [<LSPA>]
                                    [<BANDWIDTH>]
                                    [<BANDWIDTH>]
                                    [<metric-list>]
                                    [<RRO>]
                                    [<IRO>]
                                    [<LOAD-BALANCING>]
          <path-key-expansion> ::= <PATH-KEY>

It should say:

<request>::= <RP>
                    <segment-computation> | <path-key-expansion>

       where:
          <segment-computation> ::= <END-POINTS>
                                    [<LSPA>]
                                    [<BANDWIDTH>]
                                    [<metric-list>]
                                    [<RRO>[<BANDWIDTH>]]
                                    [<IRO>]
                                    [<LOAD-BALANCING>]
          <path-key-expansion> ::= <PATH-KEY>

Notes:

This document defines <path-key-expansion> to allow path request message to be used for getting the confidential path segment. The <segment-computation> should be as per RFC5440 itself.
There is a mistake in the second BANDWIDTH object which should be placed with RRO as per RFC5440.
