6.2. Optional Content-Description Header Field

The ability to associate some descriptive information with a given body is often desirable. For example, it may be useful to mark an "image" body as "a picture of the Space Shuttle Endeavor." Such text may be placed in the Content-Description header field.

   description := "Content-Description" ":" *text

The description is presumed to be given in the US-ASCII character set, although the mechanism specified in [RFC-1522] may be used for non-US-ASCII Content-Description values.
