nsIMIMEInfo extends nsIHandlerInfo with a bunch of information specific to
 MIME content-types. There is a one-to-many relationship between MIME types
 and file extensions. This means that a MIMEInfo object may have multiple
 file extensions associated with it.  However, the reverse is not true.

 MIMEInfo objects are generally retrieved from the MIME Service
