Section 5.1 says:

     <PCE-initiated-lsp-request> ::= (<PCE-initiated-lsp-instantiation>|
                                      <PCE-initiated-lsp-deletion>)

     <PCE-initiated-lsp-instantiation> ::= <SRP>
                                           <LSP>
                                           [<END-POINTS>]
                                           <ERO>
                                           [<attribute-list>]

     <PCE-initiated-lsp-deletion> ::= <SRP>
                                      <LSP>

It should say:

     <PCE-initiated-lsp-request> ::= (<PCE-initiated-lsp-instantiation>|
                                      <PCE-initiated-lsp-deletion-or-reclamation>)

     <PCE-initiated-lsp-instantiation> ::= <SRP>
                                           <LSP>
                                           [<END-POINTS>]
                                           <ERO>
                                           [<attribute-list>]

     <PCE-initiated-lsp-deletion-or-reclamation> ::= <SRP>
                                                     <LSP>

Notes:

Update needed to solve ambiguity for any extra object included after SRP and LSP objects in reclaim delegation request, which is coming from:

https://tools.ietf.org/html/rfc8281#section-6
A PCE (either the original or one of its backups) sends a PCInitiate
message that includes just the SRP and LSP objects and carries the
PLSP-ID of the LSP it wants to take control of.
