Not so.  MIME types may have more than two levels, but must have
at least two, and the requirement for creating a new top-level
type is stringent.

MIME types are a syntax standard: they tell you how to interpret
an octet-stream as something or other: currently, a picture, a sound, a
character stream, a video stream, application-specific data,
a model of a physical object, a message, or an aggregate of
one or more of these things.
