  A critical discussion is given of the results for baryon electromagnetic and
axial form factors obtained from relativistic constituent quark models in the
framework of Poincar\'e-invariant quantum mechanics. The primary emphasis lies
on the point-form approach. First we summarize the predictions of the
Goldstone-boson-exchange constituent quark model for the electroweak nucleon
structure when using a spectator-model current in point form. Then the
influences of different dynamics inherent in various kinds of constituent quark
models (Goldstone-boson-exchange, one-gluon-exchange, instanton-induced
interactions) are discussed. Finally the point-form results are compared to
analogous predictions calculated in instant form. Relativistic effects are
always of sizeable magnitude. A nonrelativistic approach is ruled out. The
instant-form results are afflicted with severe shortcomings. In the
spectator-model approximation for the current, only the point-form results
appear to be reasonable a-priori. In fact, the corresponding quark model
predictions provide a surprisingly good description of all elastic electroweak
observables in close agreement with existing experimental data, specifically
for the Goldstone-boson-exchange constituent quark model.
