Case study (this book)
It can be imagined that this book is part of a collection of 'companion' books, which conform to a standard style and layout. The editors of existing books and authors of new books are to use XML-sensitive word processors in order to ensure consistency of structure and style. All new issues will then be paginated automatically. Initial analysis will focus on one book in the range: The XML Companion.
This book was actually produced using FrameMaker+SGML, which (as the name implies) is compatible with SGML (the older brother of XML), and includes a semi-controlled authoring environment based on an SGML DTD. The following example is based on this DTD, but is simplified for XML compatibility.
