 - The generator take read jsonschema as json apply them to a set of templates
 - The generator is very basic (no json schema semantic, no `$ref` resolution) like [eventuallyconsultant/codegenr: Fast handlebars templates based code generator, ingesting swagger/openapi and other json/yaml documents with $refs, or graphql schema, outputs whatever you template](https://github.com/eventuallyconsultant/codegenr/)

 ## Why not use a jsonschema to rust generator?
 
-- I tried some and they failed (no error), maybe too early, not support for the version of jsonschema used by cdevents (often they support jsonschema draft-4)
-- The json schema (v0.3) are not connected, so lot of duplication (context,...), so classical generators will create as many Context type as Event type,... Our implementation only part of the schema is extracted to generate what is different aka the `content` of subjects.
