These rules are specific for AE invoices and shall be applied by all UAE senders who are creating invoices. Only receivers who have a receiving capability for AE invoices should apply these rule. Overseas receivers who are receiving invoices from AE but do not have a specific receiving capability for those, will only apply the shared PINT rules and may ignore these.
These are rules that are shared by all implementation of PINT compliant invoices. If any of these rules fails when validating an invoice message then that invoice is not a valid PINT invoice.
