/**
  * This interface represents an LDAPv3 control as defined in
  * <A HREF="http://www.ietf.org/rfc/rfc2251.txt">RFC 2251</A>.
  *<p>
  * The LDAPv3 protocol uses controls to send and receive additional data
  * to affect the behavior of predefined operations.
  * Controls can be sent along with any LDAP operation to the server.
  * These are referred to as <em>request controls</em>. For example, a
  * "sort" control can be sent with an LDAP search operation to
  * request that the results be returned in a particular order.
  * Solicited and unsolicited controls can also be returned with
  * responses from the server. Such controls are referred to as
  * <em>response controls</em>. For example, an LDAP server might
  * define a special control to return change notifications.
  *<p>
  * This interface is used to represent both request and response controls.
