  We show that for any weakly reflective submanifold of a compact isotropy
irreducible Riemannian homogeneous space its inverse image under the parallel
transport map is an infinite dimensional weakly reflective PF submanifold of a
Hilbert space. This is an extension of the author's previous result in the case
of compact irreducible Riemannian symmetric spaces. We also give a
characterization of so obtained weakly reflective PF submanifolds.
