Using 4D, N=1 superfield techniques, a discussion of the 6D sigma-modelpossessing simple supersymmetry is given. Two such approaches are described.Foremost it is shown that the simplest and most transparent description arisesby use of a doublet of chiral scalar superfields for each 6D hypermultiplet. Asecond description that is most directly related to projective superspace isalso presented. The latter necessarily implies the use of one chiral superfieldand one nonminimal scalar superfield for each 6D hypermultiplet. A separatestudy of models of this class, outside the context of projective superspace, isalso undertaken.Comment: 35 pages, LaTeX. v3: some comments added, version to appear in JHE
