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:AccountingSupplierParty/cac:Party | /*/cac:AccountingCustomerParty/cac:Party
Test
not($supplier) or (if ($tin = 'EI00000000030') then $selfBilled else not($selfBilled and $foreign and $general))
