BR-54 Every item attribute must have both a name and a value

noun · EN 16931 · fatal · BT-160 / BT-161

For a sample invoice, the library reports: 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.

Business term
BT-160 / BT-161
Severity
fatal

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.

A passing value

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

xpath is always a UBL path. On a CII invoice, look for the matching CII field instead.
