Documentation Request: How do I validate the schema itself?

[reitzig]

From the current documentation, it is not clear to me whether schemas are validated implicitly whenever we validate JSON against them, or failing that, how I can perform this validation.

Do I have to download the schema for JSON schema and use the normal methods, or is there built-in support?
