mod_http_oauth2: Specify that 'contacts' items are emails in client registration Not enforced, but good for documentation. > Array of strings representing ways to contact people responsible for > this client, typically email addresses. "typically" isn't a great word in a specification, so one could persume this may be e.g. URLs like https://example.com/contact-us or so as well.
