Learn more. This can be called an "absolute IRI" instead of just an "IRI". Then we don't have to make a normative statement that a fragment isn't allowed because that's part of the definition of "absolute IRI". However, it might be a good idea to clarify that fact since most people think "absolute" just means "non-relative". Which means we shouldn't need to clarify that it mean "containing a scheme" anymore. Maybe something like this would work, Suggested change [IRI](https://www.rfc-editor.org/info/rfc3987) (containing a scheme). This IRI MUST be normalized and MUST NOT contain a fragment. [absolute IRI](https://www.rfc-editor.org/info/rfc3987) (without a fragment). This IRI MUST be normalized.

		If this IRI identifies a retrievable resource, that resource SHOULD be of media
		type `application/schema+json`.
