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
$na or ($city ne '' and $state ne '' and $country ne '')
