 *  DocumentDeserializer};
 *  as well as the {@link
 *  org.openoffice.xmerge.ConverterCapabilities
 *  ConverterCapabilities} object that is specific to this format
 *  conversion.  That superclass also produces a {@link

 *  object, i.e. {@link
 *  org.openoffice.xmerge.converter.xml.sxc.DocumentMergerImpl
 *  DocumentMergerImpl} which this class derives the functionality.</p>
