Markup and formatting of preface pages
The preface pages are separate XML files that can be used for preliminary matter such as an executive summary, foreword, preface and acknowledgments. The stylesheets p5-prelims.xsl and p9-textformats.xsl have all features and instructions to set up text styles for the preface pages.
Preface pages are marked up using the <preface> element nested inside the <book> element. There are options to add a role attribute to change the order of preface pages around the book TOC and book LOTs.
