[REQ] Feature Checklist

Question:

I am currently trying to create a new generator. Before I start with the implementation I want to have a checklist what I have to implement to support all features of openapi. If that is not available I am not able to create a transparent well documented python generator with a feature list of what I already have implemented and what not.

Describe the solution you'd like

I would like to create a new markdown documentation file/guide for the generator on how to create a new generator listing all features which are supported and have to be implemented to archive a generator which is supporting all needed features to fully support the openapi-specification. For that I am trying to collect/create a full list of features which does have to be implemented to fully support the current openapi-specifications.

what this issue is about

I will start to create a checklist/featurelist in this issue which will/could be added to the project later via a pull request adding a new markdown file containing that checklist

The issue does not identify an existing file, test, or entry point. Start by collecting the features required by the current OpenAPI specifications and organize them into the proposed Markdown guide and checklist for a new generator. Done means the guide documents the feature list and allows implementation status to be recorded.
