/**
 * 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.
