I came across that doc first of all but it has little detail about the
BBC's implementation, which is vital, and has nothing on Interaction
Channel and other recent changes. The ETSI ES 202 184 V2.2.1 (2011-03)
doc is much more useful and applicable to both FreeView and FreeSat.

I believe copious amounts of garlic, silver bullets and crucifixes are
needed before speaking the 'J' word ;-)
I honestly don't think that using some unknown person(s) interpretation
of a 'secret' specification is good guidance. Pragmatically the
simplest solution is the best - just handle the currently used
extensions. Worry about further changes if/when they occur.
