/**
 * Representation of {@literal }.
 *
 *  * {@literal
 * 
 *   A 2-element JSON array that represents the UUID of a row inserted
 *   in an "insert" operation within the same transaction.  The first
 *   element of the array must be the string "named-uuid", and the
 *   second element should be the  specified as the "uuid-name" for
 *   an "insert" operation within the same transaction.  For example,
 *   if an "insert" operation within this transaction specifies a
 *   "uuid-name" of "myrow", the following  represents the
 *   UUID created by that operation:
 *
 *   ["named-uuid", "myrow"]
 *
 *   A  may be used anywhere a  is valid.  This
 *   enables a single transaction to both insert a new row and then
 *   refer to that row using the "uuid-name" that was associated with
 *   that row when it was inserted.  Note that the "uuid-name" is only
 *   meaningful within the scope of a single transaction.
 * }
