/**
 * Corresponds to the XML Schema
 * <a target="_blank" href="http://www.w3.org/TR/xmlschema-2/#token">xs:token</a> type.
 * One of the derived types based on <a target="_blank" href="http://www.w3.org/TR/xmlschema-2/#string">xs:string</a>.
 * <p>
 * A token is XML's best representation for a "whitespace insensitive string."
 * All carriage returns, linefeeds, and tabs are converted to ordinary space
 * characters (as with <a target="_blank" href="http://www.w3.org/TR/xmlschema-2/#normalizedString">xs:normalizedString</a>),
 * and furthermore, all contiguous runs of space are collapsed to single spaces,
 * and leading and trailing spaces are trimmed.
 * <p>
 * If you want <code>"&nbsp;&nbsp;high&nbsp;&nbsp;priority&nbsp;&nbsp;"</code>
 * to be equivalent to <code>"high priority"</code>, you should consider
 * using xs:token or a subtype of xs:token.
 * <p>
 * When the {@link #stringValue} is obtained from an XmlToken, the normalized,
 * trimmed, whitespace collapsed value is returned.
 * <p>
 * Convertible to {@link String}.
