Why does my UBL invoice fail with cvc-complex-type.2.3?

An element marked as element-only was given character data. The parser refuses text inside a container that may only contain child elements.

What is the difference between cvc-complex-type.2.3 and cvc-complex-type.2.4.a?

2.3 is a content-type mismatch (text vs element-only). 2.4.a is a sequence or multiplicity violation.

Can this error be auto-fixed?

The fix is often deterministic — wrap the text in the expected leaf element — but Invoice Navigator requires confirmation because the correct leaf depends on the parent type.

Where does this usually happen in Peppol invoices?

Most often inside cac:PartyName, cac:Item, cac:Country, and cac:AdditionalItemProperty.

Why does XSD forbid mixed content here?

EN 16931 uses strict element-only types so every receiver extracts field values deterministically.

Text content inside an element-only element

This is the rejection, word for word: „[cvc-complex-type.2.3] cvc-complex-type.2.3 is an XSD error raised when an element declared as element-only has non-whitespace text inside it. Mixing text and structural children is not allowed for that complex type.“

What to have readyNothing. The file has to be re-exported from your invoicing software; we check it again afterwards.

What we doMove the character data into the correct leaf element (e.g. wrap a party name in cbc:Name inside cac:PartyName).
