Rule reference

BR-54 Item attribute 1 on line 1 has neither a name (BT-160) nor a value (BT-161)

Item attribute 1 on line 1 has neither a name (BT-160) nor a value (BT-161). BG-32 is a name/value pair and EN 16931 requires both halves, because half a pair carries no information at all: a value with no name is a number nobody can interpret, and a name with no value is a question. These attributes are what a buyer's catalogue matching reads to confirm that the thing invoiced is the thing ordered — colour, capacity, licence term — so an unmatched half silently breaks that check rather than failing it visibly.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.

xpath locates the element in the generated UBL document, which is where a KoSIT or Peppol validator will report the same problem.

A passing value

the shape this field expects
"itemAttributes": [{ "name": "Farbe", "value": "anthrazit" }]

The fix

Give every entry in line.itemAttributes both a name and a value, or drop the entry. Put unstructured detail in line.longDescription (BT-154) instead.
