We have an IPLD schema language and JS tooling around it. We should find a way to integrate it into this library, specifically here are some ideas:

1. A tool that can generate capability defs from the schema definition.
   • It could generate derive functions that just fail right away.
2. Ability to generate IPLD schema from the capability definitions into a serial format.
3. Ability to generate IPLD schema in it's JSON representation
