Regarding the schemeNameCode enumeration values that are listed under the ExternalOrganisationIdentification1Code list and while format validations are provided for SREN and SRET, we could not find format details for the other codes such as: BANK, CBID, CHID, CINC, COID, CUST, DUNS, EMPL, GS1G, TXID, BDID, and BOID. Could you please confirm if there are any format validations or constraints available for these remaining codes? And provide them to us, if possible.

For the codes such as BANK, CBID, CHID, CINC, COID, CUST, DUNS, EMPL, GS1G, TXID, BDID and BOID, ISO 20022 does not provide explicit format validations.
