/**
* This class provides an implementation of an extended request that can be used
* to identify potential incompatibility problems between two backup
* compatibility descriptor values. This can be used to determine whether a
* backup from one server (or an older version of the same server) could be
* restored into another server (or a newer version of the same server). It
* may also be useful in determining whether replication initialization via
* binary copy may be performed between two servers.
*
*
* NOTE: This class is part of the Commercial Edition of the UnboundID
* LDAP SDK for Java. It is not available for use in applications that
* include only the Standard Edition of the LDAP SDK, and is not supported for
* use in conjunction with non-UnboundID products.
*
*
* The OID for this extended request is 1.3.6.1.4.1.30221.2.6.32. It must have
* a value with the following encoding:
