 # The schemas
 This folder contain the JSON schemas for the openApi specifications as used by this package.
-The original schemas from the [openApi specification repository](https://github.com/OAI/OpenAPI-Specification) have been slightly modified to work with the current AJV version that this package uses.

-- replacing $dynamicRefs by normal $refs as the current version of AJV has an issue with resolving $dynamicRefs outside the root object.
+- replacing $dynamicRefs by normal $refs as the current version of AJV has an issue with resolving $dynamicRefs outside the root object in draft-2020-12 specs.
