/**
 * This class provides an implementation of the LDAP subentries request control
 * as defined in draft-ietf-ldup-subentry.  It may be included in a search
 * request to indicate that the entries with the {@code ldapSubentry} object
 * class should be included in the search results.
 * 


 * Entries containing the {@code ldapSubentry} object class are special in that
 * they are normally excluded from search results, unless the target entry is
 * requested with a base-level search.  They are used to store operational
 * information that controls how the server should behave rather than user data.
 * Because they do not hold user data, it is generally desirable to have them
 * excluded from search results, but for cases in which a client needs to
 * retrieve such an entry, then this subentries request control may be included
 * in the search request.  This control differs from the
 * {@link RFC3672SubentriesRequestControl} in that it will cause only entries
 * with the {@code ldapSubEntry} object class to be returned, while the
 * {@code RFC3672SubentriesRequestControl} may optionally return both regular
 * entries and subentries.
 * 


 * There is no corresponding response control.
 * 


 * Example
 * The following example illustrates the use of the subentries request control
 * to retrieve subentries that may not otherwise be returned.
 *  * // First, perform a search to retrieve an entry with a cn of "test subentry"
 * // but without including the subentries request control.  This should not
 * // return any matching entries.
 * SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
 *      SearchScope.SUB, Filter.createEqualityFilter("cn", "test subentry"));
 * SearchResult resultWithoutControl = connection.search(searchRequest);
 * LDAPTestUtils.assertResultCodeEquals(resultWithoutControl,
 *      ResultCode.SUCCESS);
 * LDAPTestUtils.assertEntriesReturnedEquals(resultWithoutControl, 0);
 *
 * // Update the search request to add a subentries request control so that
 * // subentries should be included in search results.  This should cause the
 * // subentry to be returned.
 * searchRequest.addControl(new DraftLDUPSubentriesRequestControl());
 * SearchResult resultWithControl = connection.search(searchRequest);
 * LDAPTestUtils.assertResultCodeEquals(resultWithControl, ResultCode.SUCCESS);
 * LDAPTestUtils.assertEntriesReturnedEquals(resultWithControl, 1);
 * 
 *
 * @see  RFC3672SubentriesRequestControl
