  We construct a system of interacting two-sided Bessel processes on the unit
interval and show that the associated empirical measure process converges to
the Wasserstein Diffusion, assuming that Markov uniqueness holds for the
generating Wasserstein Dirichlet form. The proof is based on the variational
convergence of an associated sequence of Dirichlet forms in the generalized
Mosco sense of Kuwae and Shioya.
