It shows how to set up the development environment, create and load XML Schema models, work with namespaces, and reuse definitions across XML Schema models. This tutorial is the first of a two-part series that introduces you to XML Schema concepts and the XML Schema Infoset model."; |

| The next several panels show a set of UML |
| diagrams that represent the XML Schema Infoset model, |
| using the following notation: |
| |
| <ul><li>Each relationship or attribute Xyz, which we |
| will refer to as a feature Xyz in a diagram, |
| corresponds to a <font size="2" face="Courier New">getXyz()</font> method in Java for |
| accessing that feature.</li><li>If the feature is many-valued (in other words, (0..*)), the |
| <font size="2" face="Courier New">getXyz() method</font> returns a |
| <a href="http://java.sun.com/j2se/1.4.1/docs/api/java/util/List.html"> |
| java.util.List</a> interface, which can be modified directly using |
| standard java.util.List API.</li><li>Otherwise, if the feature is single-valued, then a |
| corresponding <font size="2" face="Courier New">setXyz()</font> method is available for |
| modification.</li></ul> |
| </p><p> |
| A relationship with a black diamond corresponds to a |
| <i>containment relationship</i>. These form the basis for the |
| concrete tree structure of the XML Schema Infoset model. |
| </p><p> |
| A relationship with a white diamond corresponds to a |
| <i>shared pseudo-containment relationship</i>. It is used only for |
| documentation purposes since it is not logically |
| different from a relationship with no diamond. In general, |
| the white diamond relationships represent relationships |
| defined directly in the |
| <a href="http://www.w3.org/TR/xmlschema-0/">XML Schema specification</a>. |
| They are typically computed from other relations |
| <b>and hence should not be modified directly</b>. |
| The exception to this rule are relations involving |
| types. These consist of base-type, member-type, |
| item-type, and element- or attribute-type. |
| </p><p><b>Note:</b> The diagrams on the next several panels can also be |
| found in the org.eclipse.xsd/src/model/XSD.mdl model |
