The feedlet chunks define the list of feedlets that are to be expected in the feed. It is a multiple-instance chunk that can express the creation, destruction, and description of feedlets dynamically. Event chunks for a feedlet must follow its corresponding feedlet creation chunk. After a feedlet is removed, there must be no more event chunks for that feedlet.
Table 6 shows the format of a Feedlet chunk body. Note that the format for entry/removal entries is different. An example of each is shown; additions and removals may appear in any order in the chunk. There can be multiple (not necessarily contiguous) descriptions entries for one feedlet.
