For Danish Suppliers if the PaymentID is prefixed with 04# or 15# the 16 digits instruction Id must be added to the PaymentID eg. "04#1234567890123456" when Payment means equals 50 (Giro)

Context
ubl-invoice:Invoice[$DKSupplierCountry = 'DK' and $DKCustomerCountry = 'DK']/cac:PaymentMeans
Test
not((cbc:PaymentMeansCode = '50') and ((substring(cbc:PaymentID, 1, 3) = '04#') or (substring(cbc:PaymentID, 1, 3) = '15#')) and not(string-length(cbc:PaymentID) = 19) )
