This isn't faulty FO.  It is a valid math expression
that subtracts a negative value, which is equivalent
to adding 4pc.

This change was to fix the wrong left margins, which were
being produced because the $title.margin.left was not
being included in the calculation.  You may recall that
printing with stylesheets 1.61 and earlier produced
overly small left margins.

This change works fine in FOP and XEP.
However, it looks like PassiveTeX's parser is not
handling the expression.  I'll have to make it
conditional on passivetex.extensions.

I don't get this error message when processing a book
with the 1.62.0 stylesheets and FOP 0.20.4 or 0.20.5.
Are you using a customization layer?
