|Identity Format||The identity format for biomes is a world name, then a comma, then the biome key. For example: 'hub,desert', or 'space,minecraft:desert'.|
|Description||A BiomeTag represents a world biome type. Vanilla biomes are globally available, however some biomes are world-specific when added by datapacks.
A list of all vanilla biomes can be found at https://minecraft.fandom.com/wiki/Biome#Biome_IDs.
BiomeTags without a specific world will work as though they are in the server's default world.
This object type is flaggable.
Flags on this object type will be stored in the server saves file, under special sub-key "__biomes"
