/**
 * Information about the party if the party is an organization.
 *
 * <div class="warning"><b>Note on International Standard versions</b><br>
 * This class is derived from a new type defined in the ISO 19115 international standard published in 2014,
 * while GeoAPI 3.0 is based on the version published in 2003. Consequently this implementation class does
 * not yet implement a GeoAPI interface, but is expected to do so after the next GeoAPI releases.
 * When the interface will become available, all references to this implementation class in Apache SIS will
 * be replaced be references to the {@code Organisation} interface.
 * </div>
 *
 * <p><b>Limitations:</b></p>
 * <ul>
 *   <li>Instances of this class are not synchronized for multi-threading.
 *       Synchronization, if needed, is caller's responsibility.</li>
 *   <li>Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases.
 *       Serialization support is appropriate for short term storage or RMI between applications running the
 *       same version of Apache SIS. For long term storage, use {@link org.apache.sis.xml.XML} instead.</li>
