  :19A::OTHR
  :19A::SETT
  :19A::STAM
  :19A::TRAX
  :19A::WITH
  :19A::COAX

• C2 If the alleged instruction is against payment (:22H::PAYM//APMT in sequence B) then it is mandatory to specify a settlement amount: one occurrence of subsequence E3 Amounts must contain amount field :19A::SETT.

  Sequence B if field :22H::PAYM is ...	Then subsequence E3 is ...	And in one occurrence of subsequence E3 :19A::SETT is ...
  APMT	Mandatory	Mandatory
  Not equal to APMT	Optional	Optional

• C3 If an Exchange Rate (field :92B::EXCH) is present, the corresponding Resulting Amount (field :19A::RESU) must be present in the same subsequence. If the exchange rate is not present then the resulting amount is not allowed. This check applies within each occurrence of subsequence E3.

  Subsequence E3 if field :92B::EXCH is ...	Subsequence E3 then field :19A::RESU is ...
  Present	Mandatory
  Not present	Not allowed

• C4 The following party fields cannot appear more than once in a message:

  Subsequence E1	Subsequence E2
  :95a::BUYR	:95a::ACCW
  :95a::DEAG	:95a::BENM
  :95a::DECU	:95a::PAYE
  :95a::DEI1	:95a::DEBT

  :95a::REAG
  :95a::RECU
  :95a::REI1
  :95a::REI2
  :95a::SELL

• C5 If the alleged instruction is a Delivery (:22H::REDE//DELI in sequence B) then it is mandatory to specify a delivering agent: one occurrence of subsequence E1 Settlement Parties must contain party field :95a::DEAG.

  If the alleged instruction is a Receipt (:22H::REDE//RECE in sequence B) then it is mandatory to specify a receiving agent: one occurrence of subsequence E1 Settlement Parties must contain party field :95a::REAG.

  Sequence B if field :22H::REDE is ...	Then in one occurrence of subsequence E1 field :95a::DEAG is ...
  DELI	Mandatory

  Sequence B if field :22H::REDE is ...	Then in one occurrence of subsequence E1 field :95a::REAG is ...
  RECE	Mandatory

• C6 If a qualifier from the list Deliverers is present in a subsequence E1, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Deliverers (see below) must be present.

  In other words, in sequence E, the following scenarios must be validated:

  • If :95a::DEI2 is present in subsequence E1, then :95a::DEI1 must be present in another subsequence E1.

  • If :95a::DEI1 is present in subsequence E1, then :95a::DECU must be present in another subsequence E1.

  • If :95a::DECU is present in subsequence E1, then :95a::SELL must be present in another subsequence E1.

  If a qualifier from the list Receivers is present in a subsequence E1, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Receivers (see below) must be present.

  In other words, in sequence E, the following scenarios must be validated:

  • If :95a::REI2 is present in subsequence E1, then :95a::REI1 must be present in another subsequence E1.

  • If :95a::REI1 is present in subsequence E1, then :95a::RECU must be present in another subsequence E1.

  • If :95a::RECU is present in subsequence E1, then :95a::BUYR must be present in another subsequence E1.

  Deliverers		Receivers
  DEI2	Deliverer's Intermediary 2	REI2	Receiver's Intermediary 2
  DEI1	Deliverer's Intermediary 1	REI1	Receiver's Intermediary 1
  DECU	Deliverer's Custodian	RECU	Receiver's Custodian
  SELL	Seller (Deliverer)	BUYR	Buyer (Receiver)

• C7 If the message is a cancellation or a removal, that is, Function of the Message (field 23G) is CANC or REMO, then subsequence A1 (Linkages) must be present at least once in the message, and in one and only one occurrence of A1, field :20C::PREV must be present; consequently, in all other occurrences of A1, field :20C::PREV is not allowed.

  Sequence A if field :23G: is ...	Then subsequence A1 is ...	And field :20C::PREV is ...
  CANC or REMO	Mandatory (minimum one occurrence of A1 must be present)	Mandatory in one occurrence of subsequence A1, and not allowed in all other occurrences of subsequence A1
  NEWM	Optional	Not applicable

• C8 In subsequence E1, if field :95a::PSET is present, then field :97a:: is not allowed in the same subsequence.

  Subsequence E1 if field :95a::PSET is ...	Subsequence E1 then field :97a:: is ...
  Present	Not allowed within the same occurrence
  Not present	Optional

• C9 A value date must only be provided for cash/securities split settlement. That is, in any occurrence of subsequence E3, if value date field :98a::VALU is present, then in sequence E field :22F::STCO//SPST must be present, and settlement amount field :19A::SETT must be present in the same subsequence E3.

  In any occurrence of subsequence E3 if field :98a::VALU is ...	Sequence E then field :22F::STCO//SPST with DSS not present is ...	In the same occurrence of subsequence E3 and field :19A::SETT is ...
  Present	Mandatory	Mandatory
  Not present	Optional	Optional

• C10 In sequence C, if field :95L::ALTE is present, then field :95a::ACOW must be present.

• C11 In sequence B, field :94a::CLEA must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::CLEA).

  In sequence B, field :94a::TRAD must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::TRAD).

  In sequence C, field :94a::SAFE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::SAFE).

  In each occurrence of subsequence E1, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE).

  In each occurrence of subsequence E2, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE).

• C12 In each occurrence of sequence F, if field :95a::ALTE is present with format option L, then field :95a::MEOR and field :95a::MERE must not be present in the same occurrence of the sequence.
