OK, the revised 19.2 now is:

19.2 Internet Media Type multipart/byteranges

When an HTTP message includes the content of multiple ranges (for
example, a response to a request for multiple non-overlapping ranges),
these are transmitted as a multipart MIME message. The multipart media
type for this purpose is called "multipart/byteranges".

The multipart/byteranges media type includes two or more parts, each
with its own Content-Type and Content-Range fields. The parts are
separated using a MIME boundary parameter.

       Media Type name:         multipart
       Media subtype name:      byteranges
       Required parameters:     boundary
       Optional parameters:     none

       Encoding considerations: only "7bit", "8bit", or "binary" are 
                                permitted

       Security considerations: none

For example:

   HTTP/1.1 206 Partial content
   Date: Wed, 15 Nov 1995 06:25:24 GMT
   Last-modified: Wed, 15 Nov 1995 04:58:08 GMT
   Content-type: multipart/byteranges; boundary=THIS_STRING_SEPARATES
   --THIS_STRING_SEPARATES
   Content-type: application/pdf
   Content-range: bytes 500-999/8000
   ...the first range...
   --THIS_STRING_SEPARATES
   Content-type: application/pdf
   Content-range: bytes 7000-7999/8000
   ...the second range
   --THIS_STRING_SEPARATES--
