Scenario : There are say two API specifications , API_Spec_1 and API_Spec_2 and they both share some schemas, say schema_1 and schema_2. While designing, I want to publish schema_1 and schema_2 to anypoint exchange, so that I can reuse them through $ref in the main API Specifcations API_Spec_1 and API_Spec_2.

How can I achieve this?

Note: In case of RAML we define raml fragments and publish them to Anypoint Exchange. I am looking for the alternative of this approach in Open API specification design in Anypoint platform.
