Module 3: Validating XML

In this lesson, participants learn what validation means. This lesson defines validation and describes its range of application. Participants learn how to identify DTDs and XDR schemas. One of the objectives of this lesson is for participants to be able to recognize DTDs and XDR schemas, and to a lesser extent read them. Participants do not need to know how to generate a DTD or an XDR schema, only to recognize one and to a limited extent, to read one.
