- New Implementation Date: The implementation date for OIOUBL 2.1 schematron version 1.17.1 has been rescheduled to Monday, May 18, 2026, at 12:00 noon (CET daylight saving time) due to the original date falling on the Friday after Ascension Day when many businesses are closed.
- Reason for Change: The Danish Business Authority recognized that the initial date would disrupt operations for e-commerce players, prompting the decision to adjust the timeline to ensure a smoother transition for all stakeholders.
- Production Requirement: It is crucial that the schematron is put into production exactly on the new implementation date to maintain consistent validation logic across the entire network, as emphasized by the Nemhandel team.
