 * The UDataInfo struct begins 4 bytes after the start of the data item,

 * with word sizes > 1 byte, char* text, or UChar* text.</p>
 *
 * <p>The implementation for the <code>udata_open[Choice]()</code>
 * functions may reject data based on the value in <code>isBigEndian</code>.
 * No other field is used by the <code>udata</code> API implementation.</p>
 *
 * <p>The <code>dataFormat</code> may be used to identify
 * the kind of data, e.g. a converter table.</p>
 *
 * <p>The <code>formatVersion</code> field should be used to
 * make sure that the format can be interpreted.
 * It may be a good idea to check only for the one or two highest
 * of the version elements to allow the data memory to
 * get more or somewhat rearranged contents, for as long
 * as the using code can still interpret the older contents.</p>
 *
 * <p>The <code>dataVersion</code> field is intended to be a

 * for data from the Unicode character database, this could
 * reflect the Unicode version.</p>
