Theorem hdmap1val 42679

Description: Value of preliminary map from vectors to functionals in the closed kernel dual space. (Restatement of mapdhval 42605.) TODO: change 𝐼 = (𝑥 ∈ V ↦... to (𝜑 → (𝐼‘⟨𝑋, 𝐹, 𝑌 > ) =... in e.g. mapdh8 42669 to shorten proofs with no $d on 𝑥. (Contributed by NM, 15-May-2015.)
