You now know how to build a DTD to define a set of rules that can be used to validate an XML document. Using DTDs, a standard set of rules can be developed that can be used to create standard XML documents. These documents can be exchanged between corporations or internally within a corporation and validated using the DTD. The DTD can also be used to create standard documents within a group, such as a group that is building an e-commerce site.

In Chapter 5, we'll look at entities. Entities enable you to create reusable strings within a DTD.
