### 2. Creating and Modifying
|
|
|
**2.1** A `Feed` class must manage the creation of frames.
|
|
|
**2.2** A `Frame` can be modified only prior to flushing (aka. transmission).
|
|
|
**2.3** Modifications after flushing are discarded.
|
|
|
**2.4** A `Frame` can only be flushed once.
|
|
|
**2.5** Modifications prior to flushing are local to the frame only.
|
|
|
**2.6** Frames are given a unique source identifier by `Feed`.
|
|
|
**2.7** `Frame` id and timestamp together are unique within the feed.
|
|
|
**2.8** Local modifications override any other change status for a channel.
