Nonetheless, I wouldn't mind blathering.

comment Wightman axioms and gauge symmetries
@user1504 I don't know much about gauge theory other than that classically, a gauge group (varying point-wise) leaves the Lagrangian invariant. I would like to know intuitively how this classical picture is supposed to manifest itself in QM and why the above requirement in my question is the mathematical image of this manifestation.
