摘要：
This remark is part of an ongoing project to simplify the structure of the multi-loop anomalous dimensions for parton distributions and fragmentation functions. It answers the call for a "structural explanation" of a "very suggestive" relation found by Moch, Vermaseren and Vogt in the context of the x -> 1 behaviour of three-loop DIS anomalous dimensions. It also highlights further structure that remains to be fully explained. (c) 2006 Elsevier B.V. All rights reserved.
