What the rule checks

As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.

Context
cac:PartyIdentification/cbc:ID[@schemeID and $isExtension]
Test
((not(contains(normalize-space(@schemeID), ' ')) and contains($ISO-6523-ICD-EXT-CODES, concat(' ', normalize-space(@schemeID), ' ')))) or ((not(contains(normalize-space(@schemeID), ' ')) and contains(' SEPA ', concat(' ', normalize-space(@schemeID), ' '))) and ((ancestor::cac:AccountingSupplierParty) or (ancestor::cac:PayeeParty)))
