    "abstract": "We discuss electromagnetic currents in the point-form formulation of\nrelativistic quantum mechanics. The construction is along a spectator model and\nimplies that only one quark is explicitly coupled to the photon, but\nnevertheless many-body contributions are present in the current operator. Such\neffects are unavoidable in relativistic constructions and resulting ambiguities\nare notably reduced by imposing charge normalization and time-reversal\ninvariance. The residual theoretical indetermination introduces small but\nsizeable changes in the nucleon form-factors, particularly at higher Q-squared\nvalues, with the data generally centered in the middle of the theoretical band.",
