/**
 * Bean that encapsulates a Hibernate type definition.
 *
 * <p>Typically defined as inner bean within a LocalSessionFactoryBean
 * definition, as list element for the "typeDefinitions" bean property.
 * For example:
 *
 * <pre class="code">
 * &lt;bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"&gt;
 *   ...
 *   &lt;property name="typeDefinitions"&gt;
 *     &lt;list&gt;
 *       &lt;bean class="org.springframework.orm.hibernate3.TypeDefinitionBean"&gt;
 *         &lt;property name="typeName" value="myType"/&gt;
 *         &lt;property name="typeClass" value="mypackage.MyTypeClass"/&gt;
 *       &lt;/bean&gt;
 *     &lt;/list&gt;
 *   &lt;/property&gt;
 *   ...
 * &lt;/bean&gt;</pre>
 *
 * Alternatively, specify a bean id (or name) attribute for the inner bean,
 * instead of the "typeName" property.
