Increase number of pagesequence masters

In a typical scenario, when using the book element as
root to
generate FO pages. Pagemaster sequences are typical
selected by e.g. the
named template
pagesetup.xsl/select.doublesided.pagemaster, where
one of
two page-sequence-masters choices are returned either
titlepage1 or
twoside1.

The current design of division.xsl (rule template "book")
uses titlepage1
as the master-reference attribute when defining the
current
fo:page-sequence for both the "titlepage",
the "preamble", and misc. table
of contents.

The twoside1 pagesequence are used for the rest of the
pages in the
document.

Allthough I could redefine book myself. I would think that
most users have
a different design for the titlepage (among other things
header and
footer) than for the rest of the pages which aso uses the
titlepage
pages-sequence, i.e. preamble, and toc.

I would therefore suggest, that the pagesetup.xsl define
an additional
pagesequence master used specificly for these "pre
document" elements,
and then only use the titlepage1 for the actual titlepage.
