+		<p>
+			The {@link org.apache.juneau.BeanContext#BEAN_useInterfaceProxies} setting (enabled by default) allows
+			the Juneau parsers to parse content into virtual beans (bean interfaces without implementation classes).
+		</p>
+		<p>
+			For example, the following code creates an instance of the specified unimplemented interface:
+		</p>
+		<p class='bcode'>
+	<jc>// Our unimplemented interface</jc> 
+	<jk>public interface</jk> Address {
+		
+		String getStreet();
+		<jk>void</jk> setStreet(String x); 
+		
+		String getCity();
+		<jk>void</jk> setCity(String x); 
+
+		StateEnum getState();
+		<jk>void</jk> setState(StateEnum x); 
+		
+		<jk>int</jk> getZip();
+		<jk>void</jk> setZip(<jk>int</jk> zip);
+	}
+	
+	<jc>// Our code</jc>
+	Address address = JsonParser.<jsf>DEFAULT</jsf>.parse(
+		<js>"{street:'123 Main St', city:'Anywhere', state:'PR', zip:12345}"</js>, 
+		Address.<jk>class</jk>
+	); 
+	
+	<jk>int</jk> zip = address.getZip();
+	address.setState(StateEnum.<jsf>NY</jsf>);
+		</p>
+		<p>
+			Getter and setter values can be any parsable values, even other virtual beans.
+		</p>
+		<p>
+			Under-the-covers, a virtual bean is simply a proxy interface on top of an existing <code>BeanMap</code>
+			instance.  From a programmatic point-of-view, they're indistinguishable from real beans, and can be 
+			manipulated and serialized like any other bean.
+		</p>	
+		<p>
+			Virtual beans can also be created programmatically using the <code>BeanContext</code> class:
+		</p>
+		<p class='bcode'>
+	Address address = BeanContext.<jsf>DEFAULT</jsf>.createSession().newBean(Address.<jk>class</jk>);
