OGC GeoPackage relies on WKB to encode geometry. The GeoPackage Vector Apollo file however seems to use EWKB, an extended version of WKB used by PostGIS and SpatiaLite.
A small hex snapshot from a maritime_limit_c feature's geometry:
47 50 00 01 E6 10 00 00 01 EE
=> E6 10 00 00 refers to 4326, which is the SRID value used by EWKB; this is not part of WKB. See also https://www.gaia-gis.it/gaia-sins/BLOB-Geometry.html.
Still present in the sprint 2 dataset.
