There isn't such a thing in Spirit. But you're the second one to ask so I
assume it has some value to implement something allowing to achieve this
behavior (a directive? i.e. noactions[...] would inhibit the execution of
all semantic actions for the embedded parser). I believe this is possible
without too much effort. I'll see what I can do.
