XML Schema

A DTD cannot easily be converted into a CREATE TABLE statement as DTD's only describe character data. The W3C defined a XML language called XML Schema that can better describe data (with proper data types).

XML Schemas can easily be converted into CREATE TABLE statements. Look at this example:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
  elementFormDefault="qualified" attributeFormDefault="unqualified">

  <xs:element name="FAQ-LIST">
		<xs:documentation>Example XML schema</xs:documentation>

		<xs:sequence maxOccurs="unbounded">
			<xs:element name="QUESTION">
						<xs:element name="QUERY"/>
						<xs:element name="RESPONSE"/>

Note: It is quite difficult to compile XML Schemas by hand. Best would be to get a tool like XMLSpy to help you to get the job done.
