Operator definitions of diffractive parton distribution functions are given. A distinction is made between the special case of ``Regge factorization'' to the general case of ``diffractive factorization'' with explicit expressions for F2diff(βx\pom, Q2;x\pom,t) in both cases. A calculation from a simple field theory model is presented in the style of ``constituent counting rules'' for the behavior of the diffractive parton distribution functions when β→ 1, which corresponds to when the detected parton carries almost all of the longitudinal momentum transferred from the scattered hadron. A comment is made about the consistency of the model with the observed flattening of n(β) as β→ 1, which recently was reported by the H1-collaboration from their preliminary 1994 data.
