How can this library be made to support additional schema formats?

[mike-schenk]

I have an AsyncAPI document that this library doesn't read properly because it uses schemaFormat: application/vnd.oai.openapi;version=3.0.0, which is one of the values that the AsyncAPI spec says implementations are recommended, but not required, to support.

The reader's diagnostics include the message

'application/vnd.oai.openapi;version=3.0.0' is not a supported format. Supported formats are application/vnd.aai.asyncapi+json, application/vnd.aai.asyncapi+yaml, application/vnd.aai.asyncapi, application/schema+json;version=draft-07, application/schema+yaml;version=draft-07

Is there an extensibility point in the Reader that will allow me to introduce support for other schema formats?

Sorry i didn't catch up with this earlier.

The current implementation is coded against the asyncapi schema format, Which differs from openapi v3 for some fields and validations.
Ill look a bit deeper into it however

Hi @mike-schenk
Ive now refactored and added support for Avro Schemas.

OAS should be easy to implement at this point.
see #170

Basically what you will need, is this;

1. Add the Schema classes (probably almost a direct copy of the AsyncApiSchema).
2. Add an AsyncApiOAIMessagePayload class that decorates the new schema type.
3. Add a deserializer (probably almost a direct copy of the AsyncApiSchemaDeserializer).
4. Add the supported schemaformat types to the AsyncApiMessageDeserializer and forward the payload loading to the prior mentioned deserializer.
5. Write tests.
