With a <property> element, Tapestry creates a read/write property of type java.lang.Object.
Alternately, you can define getter or setters in the java code, and omit the <property> element. This defines a property as well. In both cases, Tapestry provides the instance variables and the getter and setter methods in the enhanced subclass.
