Namespace Registry

To allow for creators of OpenAPI descriptions to define new extensions without the risk of name collisions, a namespace registry is maintained by OAI. The namespace registry is a simple list of unique identifiers that are used as part of a prefix for extensions to ensure uniqueness. A prefix has the format x-{namespace}- where {namespace} is a unique string associated to the creator of the extensions within the namespace. Namespace identifiers MUST be registered as lowercase identifiers.
