What will we need, beyond validation?

SimonSapin commented 3 months ago

Based on a first skim of the proposed spec:

A new built-in directive definition
Some new schema validation rules
A new rule for input coercion
- In validation, for literal object values
- In the execution engine, for variables (even though introspection, the only user of this engine for now, does not use @oneOf)
A new schema-introspection field
