/**
 * This class provides an implementation of a control which can be used to
 * request that the Directory Server include extended information when returning
 * a subschema subentry.  In the Ping Identity, UnboundID, and
 * Nokia/Alcatel-Lucent 8661 Directory Server, this will cause the server to
 * include the X-SCHEMA-FILE extension (which contains the path to the file in
 * which that schema element is defined) and the X-READ-ONLY extension (which
 * indicates whether that schema element is read-only and cannot be altered by
 * external clients).
 * 

 * 

 *   NOTE:  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.
 * 
 * 

 * This control is not based on any public specification, and has been defined
 * by Ping Identity Corporation  It does not have a value, and may or may not be
 * critical.  It should only be included in search requests.
 * 


 * 
Example
 * The following example demonstrates the procedure to use for requesting the
 * Directory Server schema with extended information.  Note that the
 * {@code LDAPInterface.getSchema} and {@code Schema.getSchema} convenience
 * methods cannot be used because they do not allow you to include controls in
 * the request.
 * 
 * String schemaDN = Schema.getSubschemaSubentryDN(connection, "");
 * SearchRequest searchRequest = new SearchRequest(schemaDN, SearchScope.BASE,
 *      Filter.createPresenceFilter("objectClass"), "*", "+");
 * searchRequest.addControl(new ExtendedSchemaInfoRequestControl());
 * SearchResult searchResult = connection.search(searchRequest);
 *
 * Schema schema = null;
 * if (searchResult.getEntryCount() == 1)
 * {
 *   schema = new Schema(searchResult.getSearchEntries().get(0));
 * }
 *
