What does UBL-CR-271 mean? A UBL invoice should not include the PayeeParty Language

Why did my invoice fail UBL-CR-271?

cac:PayeeParty/cac:Language is a UBL element with no corresponding business term in the EN 16931 semantic model, so it should not be included. The Payee group (BG-10) is limited to the payee name, identifier and legal registration identifier.

Official rule text

A UBL invoice should not include the PayeeParty Language

Common causes

Generic UBL serializer emitting a default language element for every party
Copying a full party structure from another document type (e.g. Order) into the invoice

How do I fix it?

<cac:PayeeParty>
  <cac:PartyName><cbc:Name>Payee Ltd</cbc:Name></cac:PartyName>
</cac:PayeeParty>
