There is no root element in a DTD (or in Schema); any element can be used as the document element. What this allows is partitioning documents into smaller pieces. Your directory might be huge, and I might not need all of it. You might want to send me just one person's details, but still let me validate the document. So instead of <!DOCTYPE directory SYSTEM "http://you.com/directory.dtd"> you would say <!DOCTYPE person SYSTEM "http://you.com/directory.dtd"> Ari.
