AFAIK CDXL is a not a subtype of the Interchange File Format (IFF). Here's the (only) CDXL format description I found so far. It' is from a file "CDXL.guide" (Does someone knows a better one by the way?). I can't see any relation and that's why I'll remove this IFF reference from the article.

CDXL-Format
    BYTE   8 Bit unsigned integer
    WORD  16 Bit unsigned integer, `Motorola`-Byte-Sex
    LONG  32 Bit unsigned integer, `Motorola`-Byte-Sex

CDXL-Format description [CHUNK]

#01 BYTE: $00 {0}        [CUSTOM CDXL]
 or BYTE: $01 {1}        [STANDARD CDXL]
 or BYTE: $02 {2}        [SPECIAL CDXL]

The CDXL-Info-Byte emerge by addition of the three description goups:

   #02 BYTE: $00 {0}        [RGB]        ...VIDEO ENCODING

BYTE #33 - #64 [COLORMAP] ; The pens are always WORD-coded with preceding 0s
                            i.e. each color entry has 12 Bit (4096 different colors).

z.B. 0FFF    oder  0E9A
      |||_15        |||_10          ; RGB_blue_component (0-15)
      ||__15        ||__09          ; RGB_green_component (0-15)
      |___15        |___14          ; RGB_red_component (0-15)

All of the following data ordered:@{ub}

  BITMAPDATA      [UNCOMPRESSED BODY]
