Abstract
A detailed discussion of Newtonian and general relativistic spherically sym metric dust solutions leads to the following suggested criteria for a singu larity to be classified as a shell-cross: (I) All Jacobi fields have finite limits (in an orthonormal parallel propagated frame) as they approach the singularity. (2) The boundary region forms an essential C-2 singularity whi ch is C-1 regular, that is it can be transformed away by a C-1 coordinate t ransformation.
