I think the key problem is that the game has two definitions of attack (use an attack power, make an attack roll) and quite a number of abilities that trigger off these without making it clear which one they're using.
IMO:
The Paladin's mark cares about making attacks that -target- without including him. No target = no damage. Anything else is against the spirit of the ability (and wierdly broken, as the paladin becomes much more effective against monsters that use conjurations).
Invisiblity cares about attack -powers-. Any use of an attack power -- even one that doesn't include attack rolls, will break it. If you want to run around in stance, though, that's cool.
Evasion/Minions refer to attack -rolls- doing damage; they only apply to the roll, hit, and miss lines.
Seal of Binding refers to attack -powers-. The subject of a seal of binding is immune to all effects of all attack powers, and all attacks of non-powers. This probably makes the subject immune to lava, as I'd certainly word lava as a trap that makes an attack in its space every round doing automatic damage. This is funky -- lava that was a trap wouldn't damage the target (traps do damage with attacks), but falling damage or lava that was just an environmental feature would.
However, all of this is interpretation, as there are clearly two+1/2 (ie, also "both") things that are referred to as "attacks" in the game, and only interpretation makes it clear which something is referring to.
