Expectations for uncorrelated models and models with short-range or long-range correlations are discussed and confronted to results obtained from the LEPTO and ARIADNE Monte Carlo simulations programmes.7 pages, 4 figures, to be published in the proceedings of the DESY workshop on Monte Carlo Generators for HERA physics (WG10: QCD Cascades)High Energy Physics - Phenomenologytext
