"Annex P: Tiles Encoding WebP Extension (Normative)" mentions
"The MIME type of values of the tile_data column in tile pyramid user data
tables SHALL be image/x-webp"
whereas "220.127.116.11. WEBP MIME Type" mentions :
"A GeoPackage that contains a tile pyramid user data table that contains tile
data MAY store tile_data in MIME type image/x-webp"
The first seems to imply that a tile pyramid user data declared with gpkg_webp
extension should store ONLY webp tiles, wheras the latter could be interpreted
as allowing mix of jpeg, png and webp tiles within the same tile pyramid user
Which interpretation is the correct one : first one (only webp) ?
