Ease of Development in Enterprise JavaBeans Technology

Enterprise JavaBeans (EJB) technology is a J2EE technology for developing business components in a component-based, enterprise Java application.

This sequence of characters is a paragraph. That sequence should be displayed with a link to some other information. Et cetera, et cetera. Much of the process in defining XML based on the assumption that the text in an XML document would eventually be exposed for human consumption. You can see this in the rules for what characters are allowed in XML content, what are valid characters in Names, and even in "" being required rather than just "".
