Bottom margin vs. descenders question

[Philip Taylor]

Axel, I do not understand your suggestion.  Doug has stated how he 
places a ruler at exactly one inch from the bottom of an American 
letter-sized (8.5 x 11) document, as required by the forthcoming book's 
publisher.  I do not understand how the documentation of one or two TeX 
packages is in any way relevant.  There is no suggestion that 
contributors to this book are required to work in TeX [1], let alone 
required to use the "geometry" and/or "memoir" packages, so how does 
their behaviour in any way affect Doug's task ?

[1] "The motivation for it is [that Doug has] been building a custom 
program that helps vet formatting violations for paper submissions for a 
conference and its eventual proceedings in book form.  All submissions 
are PDF, but a significant number are not created using LaTeX (Word 
usually).  There's no access to the original LaTeX source or Word file, 
which remains in authors' hands.  So the editors have to inform authors 
of all the problems and get them to fix them before resubmitting."
