 An advanced data map can provide a `DataMapValueRemover` through `AdvancedDataMapType#remover`. The remover will allow selective removals of data map values, effectively decomposition.  
 While by default a datapack can only remove the whole object attached to a registry entry, with a remover it can remove just speciffic values from the attached object (i.e. just the entry with a given key in the case of a map, or the entry with a specific property in the case of a list).  
 
-The codec that is passed to the builder will decode removers that will then be given the value currently attached and its source, and is expected to create a new object that will have the properties requested by the `remove` object removed. Alternatively, an empty `Optional` will lead to the value being completely removed.
