* This class provides an implementation of the end batched transaction extended

* created using the start batched transaction request. See the documentation
* for the {@link StartBatchedTransactionExtendedRequest} for an example of
* processing a batched transaction.

* 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.
