It does mention the "recorded stream" files with the name *.m2ts, which are 
MPEG-2 TS files. For the stream_type numbers below document says "elementary 
stream having a stream coding type of <>". The document itself refers to the 
Blu-ray standard, and such stream_type was found in m2ts file from Blu-Ray 
disk. Isn't this enough? 

I don't have access to the Blu-Ray format document itself, so I am not 100% 
sure.
