+ Yes, the <link idref="api" anchor="xml-schema-api-documentation">XML Schema
API</link>
+ defines an interface called <code>XSLoader</code> which provides methods for
loading
+ XML Schema documents into an <code>XSModel</code>. The
<code>XSImplementation</code>
+ interface provides a method to create an <code>XSLoader</code> using the
+ <jump
href="http://www.w3.org/TR/2003/CR-DOM-Level-3-Core-20031107/core.html#Bootstrap";>
+ DOM Level 3 Bootstraping mechanism</jump>. An application can get a
reference to
+ an <code>XSImplementation</code> using the <code>getDOMImplementation</code>
method
+ on the <code>DOMImplementationRegistry</code> object with the feature string
"XS-Loader".
+ To create an <code>XSLoader</code> you need to do something like this:
+ </p>
+ <source>import org.w3c.dom.DOMImplementationRegistry;
+import org.apache.xerces.xs.XSImplementation;
+import org.apache.xerces.xs.XSLoader;
+
+...

+// Get DOM Implementation using DOM Registry
+System.setProperty(DOMImplementationRegistry.PROPERTY,
+ "org.apache.xerces.dom.DOMImplementationSourceImpl");
+DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
+
+XSImplementation impl =
+ (XSImplementation) registry.getDOMImplementation("XS-Loader");
+
+XSLoader schemaLoader = impl.createXSLoader(null);
