}- simple fields
- object fields
- array fields
- constraints (see #1)
- references (see #3)
- versions (see #2)
- enums (see #5)
- generators (see #6)
- element identity
- generate java from metadata (see #4). This is lowest priority since java to metadata is lossy therefore going the other direction will require a small amount of "magic" to compute that missing information. For this reason I think it's better to simply use Java classes as the starting point / source of truth since they're much easier to write, usable in other code, and retain more information.
