OK, have a look at the samples supplied with C2. The employee sample
uses actions as does the session-state example in the CVS
version. Both illustrate different usage patterns so get the CVS
version and look at the examples.
Action sets are a way to reference a couple of actions together. Which
ones get executed is determined by a request parameter named
"cocoon-action".

Yes.

That's what they're for.
