  Amongst the diverse propositions for extra dimensional scenarios, the model
of Randall and Sundrum (RS), which offers a solution for the long standing
puzzle of the gauge hierarchy problem, has attracted considerable attention
from both the theoretical and experimental points of view. In the context of
the RS model with gauge bosons and fermions living in the bulk, a novel type of
mechanism has arisen for interpreting the strong mass hierarchy of the Standard
Model fermions. This purely geometrical mechanism is based on a type and flavor
dependent localization of fermions along a warped extra dimension. Here, we
find concrete realizations of this mechanism, reproducing all the present
experimental data on masses and mixings of the entire leptonic sector. We
consider the case of Dirac neutrino masses (due to an additional right handed
neutrino) where the various constraints on RS parameter space are taken into
account. The scenarios, elaborated in this paper, generate the entire lepton
mass hierarchy and mixing, essentially, via the higher-dimensional mechanism,
as the Yukawa coupling dependence is chosen to be minimal. In addition, from
the above mechanism, we predict the typical lepton mixing angle 10^-5 <
sin(theta_13) < 10^-1, a neutrino mass spectrum with normal hierarchy and the
smallest neutrino mass to lie approximately in the range: 10^-11 eV < m_nu_1 <
10^-2 eV. A large part of the sin(theta_13) interval should be testable in
future neutrino experiments.
