GuidelineSpecifiedDocumentContextParameter

This CII element states which guideline or profile (EN 16931, Factur-X) an invoice claims to conform to.

Definition

In CII syntax (Cross Industry Invoice, UN/CEFACT) a document's context is described by an ExchangedDocumentContext group. Within it, GuidelineSpecifiedDocumentContextParameter holds an identifier (ID) that precisely names the guideline or profile the document claims to follow.

Role

This element lets a receiver or validator know which business rules to apply. Its value is a URN identifying, for example, the core of EN 16931 or a specific Factur-X profile (BASIC, EN 16931, EXTENDED).

• On the UBL side the equivalent role is played by the CustomizationID element.
• A second element, BusinessProcessSpecifiedDocumentContextParameter, declares the business process (the equivalent of UBL's ProfileID).

Good to know

The identifier value must match exactly the URN expected by the target specification; an incorrect string fails validation even when the rest of the invoice is correct. It is often the first thing a conformance checker inspects.
