Chapter 1. Introduction
In the next two chapters, I’m going to give you a crash course in XML and constraints. Since there is so much material available on XML and related specifications, I’d rather cruise through this material quickly and get on to Java. For those of you who are completely new to XML, you might want to have a few of the following books around as reference:
XML in a Nutshell, by Elliotte Rusty Harold and W. Scott Means
Learning XML, by Erik Ray
Learning XSLT, by Michael Fitzgerald
XSLT, by Doug Tidwell
These are all O’Reilly books, and I have them scattered about my own workspace. With that said, let’s dive in.
XML 1.0
It all begins with the XML 1.0 Recommendation, which you can read in its entirety at http://www.w3.org/TR/REC-xml. Example 1-1 shows an XML document that conforms to this specification. I’ll use it to illustrate several important concepts.
Example 1-1. A typical XML document is long and verbose
