- Level: error
- Rule sets: Croatian eRačun rules (UBL) 13.03.2026
- Context: `ubl-creditnote:CreditNote | ubl-invoice:Invoice`
- Test: `normalize-space(cbc:CustomizationID) = 'urn:cen.eu:en16931:2017#compliant#urn:mfin.gov.hr:cius-2025:1.0#conformant#urn:mfin.gov.hr:ext-2025:1.0'`

In English: The specification identifier (BT-24) must be 'urn:cen.eu:en16931:2017#compliant#urn:mfin.gov.hr:cius-2025:1.0#conformant#urn:mfin.gov.hr:ext-2025:1.0'.

## Why it fails

- `cbc:CustomizationID` holds the plain EN 16931 or Peppol identifier, or an older Croatian one.

## How to fix it

- Set `cbc:CustomizationID` to `urn:cen.eu:en16931:2017#compliant#urn:mfin.gov.hr:cius-2025:1.0#conformant#urn:mfin.gov.hr:ext-2025:1.0`.
