I remember someone contributed this kind of documentation in the past.
Here it is:

http://benno.id.au/docs/lttng_data_format.pml

I'm unsure which version of the format it applies to though. It's best
to confirm if it matches the source files before assuming it fits lttng
0.x trace format 2.6.

Good luck!
