The geometry coordinate system can have both right-handed and left-handed data.
It is a specification that allows its own definition extension (chunk, schema).
It is designed to support partial encryption.
Resources are basically included in a file, but they can be cut out in another file.
Resources can compress data with sparse, and have their own definition of the more powerful sparse.
