At the WWP we do not use PROLOGUE and EPILOGUE elements. They have
been removed from our DTD. Instead we use DIV elements with type=
values of 'prologue' and 'epilogue'. This way the DIV for an epilogue
or prologue can be stuck in FRONT, BODY, or BACK, depending on where
it seems appropriate.
Prologues to plays or novels, where such a prologue was written
to be performed with the play, or to be read with the novel,
rather than to introduce a particular edition, should be
encoded using <div type="prologue"> as part of the BODY
element, unless some other indisputably FRONT-like element
 By declaring the parameter entities %prologue; and %epilogue; to
"IGNORE" in our local extensions .ent file. Easier to just use

 I just realized that "indisputably FRONT-like element" should
probably be something less colloquial, like "element which
indisputably belongs in FRONT".
