* Indicates if derived elements can inherit the value of this property.
	 * Most properties can inherit values from a parent element. A few system
	 * properties, such as the name or extends, can't be inherited.
	 * <p>
	 * Note: This attribute is used for both style property and non-style
	 * property with two different meanings.
	 * <ul>
	 * <li>For style property, it determines whether this property can be
	 * cascaded from container;
	 * <li>For non-style property, that means whether this property can be
	 * inherited from parent.
	 * </ul>
	 * We take it because of the fact style is not inheritable, and the
	 * following diagram:
	 * <p>
	 * <table border="1" cellpadding="2" cellspacing="2" style="border-collapse:
	 * collapse" bordercolor="#111111">
	 * <th width="20%"></th>
	 * <th width="40%">can inherit</th>
	 * <th width="40%">can cascade</th>
	 * <tr>
	 * <td>Style property</td>
	 * <td align="center"><code>false</code></td>
	 * <td align="center"><code>isInheritable</code></td>
	 * </tr>
	 * <tr>
	 * <td>Non-style property</td>
	 * <td align="center"><code>isInheritable</code></td>
	 * <td align="center"><code>false</code></td>
	 * </tr>
