  We show that bimodal systems with a spatially nonuniform defocusing cubic
nonlinearity, whose strength grows toward the periphery, can support stable
two-component solitons. For a sufficiently strong XPM interaction, vector
solitons with overlapping components become unstable, while stable families of
solitons with spatially separated components emerge. Stable complexes with
separated components may be composed not only of fundamental solitons, but of
multipoles too.
