<!-- [rfced] We have two questions about the definition below:
a) Does "to be defined" need further clarification, perhaps "to be defined in
future specifications"?
b) Section 20.3 defines value 0 as "matroska script" and value 1 as "menu
borrowed from the DVD [DVD-Video]". Should the definitions match? Or is the
current okay?
Original:
definition: Contains the type of the codec used for the processing.
A value of 0 means built-in Matroska processing (to be defined), a
value of 1 means the DVD command set is used; see Section 20.3 on
DVD menus.
