The constructive solution to a correspondence $(\xi\sb t)\sb{t\ge 0}\to\{{\cal C},w\sb c\}$, which becomes one-to-one when $\{{\cal C},w\sb c\}$ can be given a probabilistic interpretation, is described. In particular we show that the L\'evy-Austin-Ornstein theorem concerning the positiveness of the transition probabilities $p\sb{ij}(\cdot)$ is a qualitative property. Also it is proved that the intensities $q\sb{ij}$ have a probabilistic interpretation in terms of the sample paths of the discrete skeletons. Finally, analytical properties of the weight functions are studied.}, identifier = {00027220}, }
