Of course they are, they are at a much lower level than the cap on (say) KLAX Class B. I suggest you have a look at the whole vertical structure of ICAO/FAA airspace in US.
If there is E over B,C,D the rules for E apply in E.
It is that simple.

Shouldn't be too hard to find, of course the "VFR private" pilots was castigated, until a few loudmouths found out he was a highly experienced professional pilot. Look up the ATSB lists. The issue I am raising is that the airline aircraft, having been given traffic, turned towards the "threat", was never able to produce a plausible and convincing explanation for the turn.
Tootle pip!!
