CII-DT-035: Remove unitCodeListAgencyID from quantities

In short

Fatal: fails the selected checks.

CII-DT-035 means a CII quantity carries unitCodeListAgencyID, an attribute identifying the agency behind its unit code list. Remove that attribute while keeping the intended unitCode.

What it means

The check applies to every CII ram element whose name ends in Quantity. It requires unitCodeListAgencyID to be absent. It does not check the unitCode value or require a unitCode to be present. A billed quantity's unit of measure is BT-130.

Why it matters

This CII mapping does not permit the code list agency identifier on quantities. The unit of measure is recorded separately in unitCode.

How to fix it

Remove unitCodeListAgencyID from each affected quantity. Do not remove or change unitCode just to resolve this rule. If your software inserts the agency identifier, ask its supplier to correct the CII export. Export the corrected file and recheck it.
