40 * doing, but this matching can be tricky see 7.8.1 Coupling of C-Plane and U-Plane
41 * - Detect/indicate signs of application layer fragmentation?
42 * same eAxC in same symbol (same/different section ID?)
43 * - Not handling M-plane setting for "little endian byte order" as applied to IQ samples and beam weights
44 * does anyone use this?
45 * - for section extensions, check more constraints (which other extension types appear with them, order, repeated)
46 * - re-order items (decl and hf definitions) to match spec order?
47 * - track energy-saving status, and identify TRX or ASM commands as 'Sleep extension'
48 * - attempt to show (at least when section Ids are used) which beamId is associated with each DL U-Plane section
