I would, for now, ignore the COMMAND part and only concern
ourselves with the non-action soap things.

I would propose to have S, O, A, P matcher objects or, in case
instantiation fails, assign Null design pattern instances.

Is there a way to keep track of which section one is in so we
know which matcher to use ? I would also propose to currently
constrain ourselves to matching single words only, not
entire phrases. Maybe later.

I would try to keep that possible but do it later.

Yes.
