fatalPeppol BIS Billing 3.0profileUBLBT-30
If seller is icelandic then it shall contain sellers legal id — Ef seljandi er íslenskur þá skal reikningur innihalda íslenska kennitölu seljanda (BT-30).
The Icelandic seller's kennitala (national identifier) is missing.
Add the ten-digit kennitala as the seller's legal registration identifier (BT-30).
UBL — context ubl-creditnote:CreditNote[$SupplierCountry = 'IS'] | ubl-invoice:Invoice[$SupplierCountry = 'IS']
exists(cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:CompanyID) and cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:CompanyID/@schemeID = '0196'
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
