Re: [ubl-psc] Multiple identifiers for certain items

[Oriol Bausą Peris <oriol@invinet.org>]

Hi Ken,

Reading your mail, it reminds me to the identification of parties, having a cac:PartyIdentification/cbc:ID, where the PartyIdentification ABIE is unbounded. Shouldn't we try to use the same approaches?

Best regards, Oriol
