- *   - generic container system items

+ *   - Implement support for DMS-1 and descriptive metadata tracks
+ *   - Differentiate UL and UUIDs, the former can define an object system

+ *     The latter are just 16 byte unique identifiers
+ *   - Check everything for correctness vs. SMPTE S336M, some things can probably
+ *     be generalized/simplified
+ *   - Correctly timestamp essence streams and start/stop at the correct positions.
+ *     Also switch between different structural components after one has ended.
+ *   - Seeking support: IndexTableSegments and skip-to-position seeks, needs correct
+ *     timestamp calculation, etc.
+ *   - Handle timecode tracks correctly (where is this documented?)
+ *   - Handle Generic container system items
+ *   - Use an "essence element/track handling" registry instead of the large if-then-else
+ *     block when detecting the codec
+ *   - Force synchronization of tracks. Packets that have the timestamp are not required
+ *     to be stored at the same position in the essence stream, especially if tracks
+ *     with different source packages (body sid) are used.
+ *   - Implement correct support for clip-wrapped essence elements.
+ *   - Add a "tracks" property to select the tracks that should be used from the
+ *     selected package.
+ *   - Post structural metadata and descriptive metadata trees as a message on the bus
+ *     and send them downstream as event.
+ *   - Multichannel audio needs channel layouts, define them (SMPTE S320M?).
+ *   - Correctly handle the different rectangles and aspect-ratio for video
+ *   - Add support for non-standard MXF used by Avid (bug #561922).
+ *
+ *   - Implement SMPTE D11 essence and the digital cinema/MXF specs
