#24579 new defect

boundaries.osm does not contain all exclaves

Description

Basically, I have been told the JOSM team maintains the boundaries.osm file, and I have an issue with that file.

TL;DR: the boundaries.osm file does not contain all exclaves, which causes issues downstream. This may have something to do with multipolygon boundaries not being correctly extracted from OSM data.

This issue was discovered downstream while reviewing the boundaries of both Hong Kong and Macao. For more background (downstream) information, (e.g. illustrative diagrams, explanations, ...), see e.g. ​https://github.com/westnordost/countryboundaries/issues/25 and also ​https://github.com/graphhopper/graphhopper/issues/3253

If you provide a patch we'll apply it.

P.S. Boundaries file was never meant to be an exact representation of the political situation of the world. That's simply too fast changing and has too many disputed situations. It's simply a means to apply certain country specific rules.
