Re: [docbook] Question to cutomization of docbook-xsl

["Bob Stayton" <bobs at sagehill dot net>]

I got a reply back from the XEP mailing list about this problem.
It turns out that the default value for the force-page-count property
is "auto".  According to the XSL-FO spec 7.25.6:

"Force it to be an even-page if the initial-page-number
of the next page sequence is odd."

So the preface page sequence  was forcing the extra page because
the following chapter page sequence had initial-page-number="1".

The solution is to add force-page-count="no-force" to the
preface page sequence when double-sided output is turned off.
I just checked in this change to fo/component.xsl.  I'll see if
other templates need such a change as well.
