/**
* This class provides an implementation of a get changelog batch change
* selection criteria value that indicates that the server should not return
* changes which target only the specified attributes. This can be useful for
* ignoring changes to attributes which are changed frequently but not of
* interest to the client. Note that changes returned may include changes to
* these attributes, but only if the change targets other attributes that should
* not be ignored.
*
*
* 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.
