* The FD item information box is optional, although it is mandatory for files
* using FD hint tracks. It provides information on the partitioning of source
* files and how FD hint tracks are combined into FD sessions. Each partition
* entry provides details on a particular file partitioning, FEC encoding and
* associated FEC reservoirs. It is possible to provide multiple entries for one
* source file (identified by its item ID) if alternative FEC encoding schemes
* or partitionings are used in the file. All partition entries are implicitly
* numbered and the first entry has number 1.
