% Gerald Gazdar (1992) "Paradigm function morphology in DATR", in Lynne
%   Cahill & Richard Coates, eds. Sussex Papers in General and Computational
%   Linguistics, Cognitive Science Research Paper CSRP 239, University of
%   Sussex, pages 43-53.
%
%   This paper shows how Stump's "paradigm function" (PFM)
%   approach to inflectional morphology can be implemented in
%   DATR.  PFM analyses can be encoded in DATR without any loss
%   in concision over Stump's own notation, but with a great
%   gain in generality, since Stump's notation is ad hoc to PFM
%   analyses of inflectional morphology.  DATR is thus to be
%   preferred to Stump's own notation on general methodological
%   grounds.  An appendix suggests that there may also be
%   analytical grounds for preferring DATR in view of the
%   difficulties that the Swahili object agreement facts cause
%   for Stump's notation.
