 * : The carvers to use.
 * : (Optional, can be empty) List of carvers used during the  cave generation step. Can be an id of a configured carver, a tag of configured carvers, or a configured carver object, or a list of configured carver IDs, or a list of configured carver objects.
 * : (Optional, can be empty) List of carvers used during the  cave generation step. Currently doesn't work. Can be an id of a configured carver, a tag of configured carvers, or a configured carver object, or a list of configured carver IDs, or a list of configured carver objects.
 * : (Can be empty) A list of 11 elements. Each element can be a tag of placed feature, a list of placed feature IDs, or a list of placed feature objects. The features are applied to each chunk in order in each step. The same placed feature in the same step in two biomes cannot be in a different order. For each step, all feature IDs need to be ordered consistently across biomes. For example, in minecraft:plains in UNDERGROUND_ORES step, ore_dirt is before ore_gravel, so in other biomes' UNDERGROUND_ORES step, if there are ore_dirt and ore_gravel, ore_gravel cannot be after ore_dirt. The generation steps are also used in stucture features.

 * : Generation step . Used for trees, bamboo, cacti, kelp, and other ground and ocean vegetation in vanilla.
 * : Generation step . Used for surface freezing in vanilla.
 * : (optional) Higher value results in more creatures spawned in world generation. Must be between 0.0 and 0.9999999 (both inclusive).
