Is the Burst ID just a sequence of octets?

For the moment, the Burst ID  is a uint64_t. Should this not be not enough
in future implementations, it can be increased to e.g. uint128_t

So it should be treated as an opaque array of bytes, with no significance to the values of the bytes, and used only for 
matching bursts and the MAC frames contained within them by comparing the byte arrays for equality?

What does the Burst ID Reference field contain?  Another burst ID?

The Burst ID reference is the same as the Burst ID. Burst IDs are used in
databursts, while Burst ID references are used in Mac Frames. For the
moment, these are both uint64_t.

I.e., one or more MAC frames can be transmitted in a burst, and a capture can contain a record for a burst as well as 
records for the MAC frames within the burst, with the record for the burst having a Burst ID parameter, and all the 
records for the MAC frames in that burst have a Burst ID Reference parameter containing the burst ID value for the 
burst in which it appeared?
