In extradimensional holographic approaches the flavor symmetry is gauged in the bulk, that is, treated as a local symmetry. Imposing such a local symmetry admits fewer terms coupling the (axial) vectors and (pseudo)scalars than if a global symmetry is imposed. The latter is the case in standard low-energy effective Lagrangians. Here we incorporate these additional, a priori only globally invariant terms into a holographic treatment by means of a St"uckelberg completion. This work was motivated by our investigations concerning dynamical electroweak symmetry breaking by walking technicolor and we apply our findings to these theories.
