/**
 * This class provides an implementation of a request control that may be used
 * to encapsulate a set of zero or more other controls represented as JSON
 * objects, and to indicate that the server should return any response controls
 * in a {@link JSONFormattedResponseControl}.
 * <BR>
 * <BLOCKQUOTE>
 *   <B>NOTE:</B>  This class, and other classes within the
 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
 *   supported for use against Ping Identity, UnboundID, and
 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
 *   for proprietary functionality or for external specifications that are not
 *   considered stable or mature enough to be guaranteed to work in an
 *   interoperable way with other types of LDAP servers.
 * </BLOCKQUOTE>
 * <BR>
 * This control has an OID of 1.3.6.1.4.1.30221.2.5.64, and it may optionally
 * take a value.  If the control is provided without a value, then it merely
 * indicates that the server should return response controls in a
 * {@code JSONFormattedResponseControl}.  If the control has a value, then that
 * value should be a JSON object that contains a single field,
 * {@code controls}, whose value is an array of the JSON representations of the
 * request controls that should be sent to the server.  The JSON representations
 * of the controls is the one generated by the {@link Control#toJSONControl()}
 * method, and is the one expected by the {@link Control#decodeJSONControl}
 * method.  In particular, each control should have at least an {@code oid}
 * field that specifies the OID for the control, and a {@code criticality} field
 * that indicates whether the control is considered critical.  If the control
 * has a value, then either the {@code value-base64} field should be used to
 * provide a base64-encoded representation of the value, or
 * the {@code value-json} field should be used to provide a JSON-formatted
 * representation of the value for controls that support it.
 * <BR><BR>
 * The criticality for this control should generally be {@code true}, especially
 * if it embeds any controls with a criticality of {@code true}.  Any controls
 * embedded in the value of this control will be processed by the server with
 * the criticality of that embedded control.
