Validating xml scema
When sending data from a sender to a receiver, it is essential that both parts have the same "expectations" about the content.
With XML Schemas, the sender can describe the data in a way that the receiver will understand. However, an XML element with a data type like this: Even if documents are well-formed they can still contain errors, and those errors can have serious consequences.
An XML document with correct syntax is called "Well Formed".
An XML document validated against an XML Schema is both "Well Formed" and "Valid".
Mainly we will address the differences between DTD and XML Schema definitions discussed in earlier volumes, and element and attribute declarations using XML Schema.
This is knowledge required for being able to answer questions in Section 4 "XML Schema" in the XML Master Basic V2 Exam, so let’s be sure to establish a solid grasp in this area.
From this page you can find out more about DTDs and W3C XSD, since those are the primary schema languages defined at W3C.

DTD has a characteristically simple syntax for functions and content definition.
