Hi,

waiting on part 7 with baited breath. Now many of these Elba islets are highlighted as needing an inner role. Since there are two lines each, both with outer, think last time the 'outer' correction landed on the wrong outline. So my interpretation, that all in the Elba relation need to be outer and those with the Santuaire Pelagos need to be inner. Took me a long time to load all members into JOSM than dragged a islet node to kick the validator and sure the MP is not working, warning there is a style on member outlines members.

Personally I'd tag this as a boundary as it is now and removing all the 'inner' as everything inside the SP sea zone is automatically part of the reserve. Maybe another reader of this has comment to this.
