Generalised Shafarevich conjecture for Shimura-type integral structures

Let K=KlKlK=K^lK_l be a neat compact open subgroup of G(Af)G(\mathbb A_f), let x=[s,1]x=[s,\overline{1}] be a point of ShK(G,X)(L)Sh_K(G,X)(L), and fix a lift x~=[s,1]\widetilde{x}=[s,1] in ShKl(G,X)Sh_{K^l}(G,X). Let (VZ,s,ρx~,l)(V_{\mathbb Z},s,\rho_{\widetilde{x},l}) be the corresponding (,l)(\infty,l)-integral structure of Shimura type. Generalised Shafarevich conjecture. The set of (,l)(\infty,l)-integral structures of Shimura type that are ll-isogeneous to (VZ,s,ρx~,l)(V_{\mathbb Z},s,\rho_{\widetilde{x},l}) contains only finitely many isomorphism classes. The paper studies this finiteness assertion and its relation to the Isogeny conjecture; the source does not state that it has been resolved.
