 Multimedia Email Extensions (MIME) define the types of media that are used on the Internet. RFC1521 and RFC1522 specify the types and subtypes for MIME. The  directory ftp://ftp.isi.edu/in-notes/iana/assignments/media-types/ also describes these types. The x- prefix for the content-type indicates that the extension is not considered a standard type and may change or be defined otherwise by other users.
