-/**
- * Interface for messages with machine-readable data for use by the API
- *
- * The idea is that it's a Message that has some extra data for the API to use when interpreting it
- * as an error (or, in the future, as a warning). Internals of MediaWiki often use messages (or
- * message keys, or Status objects containing messages) to pass information about errors to the user
- * (see e.g. Title::getUserPermissionsErrors()) and the API has to make do with that.
- *
- * @since 1.25
- * @note This interface exists to work around PHP's inheritance, so ApiMessage
- * can extend Message and ApiRawMessage can extend RawMessage while still
- * allowing an instanceof check for a Message object including this
- * functionality. If for some reason you feel the need to implement this
- * interface on some other class, that class must also implement all the
- * public methods the Message class provides (not just those from
- * MessageSpecifier, which as written is fairly useless).
