 * Represents a template definition.
 * Following are some of the most common properties you can use to configure your templates. Of course, if you're using specific subclasses, other properties could be available.

 * <tbody>
 * <tr>
 * <th>Name of Property</th>
 * <th>Default Value</th>
 * <th>Value Example or Range</th>
 * <th>Description</th>

 * <tr>
 * <td>class</td>
 * <td>{@link Template}</td>
 * <td>&nbsp;</td>
 * <td>&nbsp;</td>
 * </tr>
 * <tr>
 * <td>type</td>
 * <td> <code>jsp</code></td>
 * <td> <code>jsp</code>, <code>freemarker</code>, �</td>
 * <td>Determines which <code>TemplateRenderer</code> to use. Out of the box,
 * Magnolia provides support for JSP and FreeMarker.</td>
 * </tr>
 * <tr>
 * <td>templatePath</td>
 * <td>&nbsp;</td>
 * <td>Conventional path syntax is used for this property.</td>
 * <td>This property defines the URI to the template which is normally a JSP.
 * The path for the template is relative to the root and structure of the webapp
 * folder.</td>
 * </tr>
 * <tr>
 * <td>visible</td>
 * <td><code>true</code></td>
 * <td><code>true</code>, <code>false</code></td>
 * <td>This property determines if the template is visible in the template
 * drop-down list. If a template is to be restricted so that only certain users
 * can see it in the drop-down list, a role needs to be defined in security
 * which denies access to the particular template definition content node.</td>
 * </tr>
 * <tr>
 * <td>modelClass</td>
 * <td>&nbsp;</td>
 * <td>The fully qualified name of a class implementing {@link RenderingModel}
 * </td>
 * <td>The bean created by the renderer based on the modelClass defined on the
 * paragraph or template definition. The current content, definition and the
 * parent model are passed to the constructor. This object is instantiated for
 * each rendering of a template or a paragraph.</td>
 * </tr>
 * <tr>
 * <td>subTemplates</td>
 * <td>&nbsp;</td>
 * <td>Any valid node identifier.</td>
 * <td>This property designates a node containing any subtemplates to be used by
 * the template.</td>
 * </tr>
 * <tr>
 * <td>name</td>
 * <td>nodeName</td>
 * <td>Naming conventions should be followed using standard alphanumerical
 * characters only.</td>
 * <td>This property lists the name of the template.</td>
 * </tr>
 * <tr>
 * <td>i18nBasename</td>
 * <td>&nbsp;</td>
 * <td>Naming conventions should be followed using standard alphanumerical
 * characters only.</td>
 * <td>This property defines the message bundle to use for this template.</td>
 * </tr>
 * <tr>
 * <td>title</td>
 * <td>&nbsp;</td>
 * <td>The title or a message bundle key to be used with the bundle defined by
 * <code>i18nBasename</code>.</td>
 * <td>This property designates the title of the template. The i18nBasename
 * (designated message bundle) renders the title.</td>
 * </tr>
 * <tr>
 * <td>description</td>
 * <td>&nbsp;</td>
 * <td>The description or a message bundle key to be used with the bundle
 * defined by <code>i18nBasename</code>.</td>
 * <td>This property contains the description of the template. Descriptions
 * should be intuitive and provide a context for users and/or developers to
 * understand how the overall template functions.</td>
 * </tr>
 * </tbody>
 * </table>
 *
 * @deprecated since 4.5, the differentiation of paragraphs and templates were removed. Use {@link RenderableDefinition} instead.
