3Introduction to XML




Now consider the following XML document:

<book image=”xslt.gif”>

<title>XSLT Programmers Reference</title>
<author>Michael Kay</author>
<year>2003</year>

</book>

The image attribute contains additional information that an application might use to display the book
information with a picture. Because no one other than the software processing this document is likely to
care about the image, and because the image is an adjunct to (rather than a part of) the book’s definition,
image is properly cast as an attribute instead of an element.
