/**
 * The TextSpacingSC represents CSS "word-spacing" and "letter-spacing" values.
 * The allowed values are:
 * <ul style="font-family: monospace;">
 *         <li> normal </li>
 *         <li> [specific length value] - a length value (i.e. units are %, px, in, etc.
 *              but % CANNOT be used for this type!) </li>
 * </ul>
 * <br /><br />
 * The <code>StyleComponent</code> (SC) is the most basic of the three building pieces
 * of CSS styles. It combines a CSS property value with a ValidatorRule to ensure that
 * the value follows a certain format.<br /><br />
