InstructionTypeCode should not be present
'SupplyChainTradeTransaction/ApplicableHeaderTradeSettlement/SpecifiedTradePaymentTerms/InstructionTypeCode' is present, but this profile does not allow it — nothing in the EN 16931 semantic model maps to it. The rule text names only 'InstructionTypeCode'; the path above is where the rule actually looks.
Remove 'SupplyChainTradeTransaction/ApplicableHeaderTradeSettlement/SpecifiedTradePaymentTerms/InstructionTypeCode'. It is almost always left over from a generic template or a library that emits every field of the underlying schema. Reported as a warning.

Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
