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 <i>QName prefix namespace map</i> stores a
prefix as the keys and namespace Uri as the values. This
QName prefix namespace map is stored on the root
XSDSchema object and is used when XSDNamedComponents
need to be resolved.
</p><p>
If you want to add additional prefix-namespace pairs to
a given XML Schema file, you can do the following:
</p><pre><font size="2" face="Courier New">
//Add additional prefix-namespace pair xmlns:address="http://www.eclipse.org/xsd/examples/address"
qNamePrefixToNamespaceMap.put("address","http://www.eclipse.org/xsd/examples/address");
