55 Deviations from the PEL series

In some cases, however, the model rules which the reader encounters in this DCFR deviate from their equivalent published in the PEL series. There are several reasons for such changes. First, in drafting a self-standing set of model rules for a given subject (such as e. g. service contracts) it proved necessary to have much more repetition of rules which were already part of the PECL. Such repetitions became superfluous in an integrated DCFR text which states these rules at a more general level (i. e. in Books II and III). The DCFR is therefore considerably shorter than it would have been had all PEL model rules been included as they stood.
