C3
If the instruction is a delivery (:22H::REDE//DELI in sequence B) and subsequence B1 Settlement Parties is used, then it is mandatory to specify a receiving agent: one occurrence of subsequence B1 Settlement Parties must contain party field :95a::REAG (Error code(s): E85).
If the instruction is a receipt (:22H::REDE//RECE in sequence B) and subsequence B1 Settlement Parties is used, then it is mandatory to specify a delivering agent: one occurrence of subsequence B1 Settlement Parties must contain party field :95a::DEAG (Error code(s): E85).

In other words, in sequence B, the following scenarios must be validated:
If :95a::DEI9 is present in subseq B1, then :95a::DEI8 must be present in another subseq B1.
If :95a::DEI8 is present in subseq B1, then :95a::DEI7 must be present in another subseq B1.
If :95a::DEI7 is present in subseq B1, then :95a::DEI6 must be present in another subseq B1.
If :95a::DEI6 is present in subseq B1, then :95a::DEI5 must be present in another subseq B1.
If :95a::DEI5 is present in subseq B1, then :95a::DEI4 must be present in another subseq B1.
If :95a::DEI4 is present in subseq B1, then :95a::DEI3 must be present in another subseq B1.
If :95a::DEI3 is present in subseq B1, then :95a::DEI2 must be present in another subseq B1.
If :95a::DEI2 is present in subseq B1, then :95a::DEI1 must be present in another subseq B1.
If :95a::DEI1 is present in subseq B1, then :95a::DECU must be present in another subseq B1.
If :95a::DECU is present in subseq B1, then :95a::SELL must be present in another subseq B1.
If a qualifier from the list Receivers is present in a subsequence B1, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Receivers (see below) must be present.

If :95a::RECU is present in subseq B1, then :95a::BUYR must be present in another subseq B1.
C5
In subsequence B1, if field :95a::PSET is present, then field :97a::SAFE is not allowed in the same subsequence (Error code(s): E52).
C6
Within each occurrence of subsequence A2a, the qualifier in field 24B must be the same as the code word (Status Code) used with the appropriate qualifier in field 25D of its surrounding subsequence A2 (Error code(s): E37).
(*) if the Data Source Scheme is present in field :25D:: then the conditional rule does not apply.
A reference to the previously received message must be specified, i.e. field 20C::RELA must be present in one and only one occurrence of Subseq. A1 Linkages; field 20C::RELA is not allowed in all other occurrences of Subseq. A1 (Error code(s): C73).
