Let X be a compact Hausdorff space, E be a real Banach space and A be a linear space of continuous functions of X into E , separating points and containing constants. Let M ( X , E * ) be the space of regular E * ‐valued measures on X of bounded variation. For E = C , Roth has shown that M ( X , C ) may be ordered in such a way that the maximal measures are precisely the boundary measures for A . This ordering is extended to a general E , and it is shown that the appropriate existence and uniqueness theorems can be deduced from real Choquet theory by transferring E * ‐valued measures on X into positive measures on X ×E 1 ∗ .
