If you need a new format that has not yet been defined in our <xref

guidelines on mimetype naming, properties and such. A mimetype would
ideally be one defined by IANA; else, it should be in the form
type/x-name, where type is the sort of data this mimetype handles (audio,
video, ...) and name should be something specific for this specific type.
Audio and video mimetypes should try to support the general audio/video
properties (see the list), and can use their own properties, too. To get
