Schema Enum Description
Annexes, chapters and items of the European schedule of occupational diseases (Commission Recommendation 2003/670/EC as amended by 2022/2337 and 2025/2609). Items point to their chapter, and chapters to their annex, via ``is_a``. Assign the most specific applicable item. Annex II values (``suspected_*``) record a SUSPECTED occupational aetiology, not an established one. ``source`` on this enum is the consolidated instrument. Individual values carry their own ``source`` ONLY where the item was introduced by an amendment rather than by the 2003 base schedule, so a per-value ``source`` is a positive signal that the item is a recent addition.
