For #12 ,

from galera::Certification::do_test in certification.cpp:

    if (trx->version() != version_)
    {
        log_warn << "trx protocol version: "
                 << trx->version()
                 << " does not match certification protocol version: "
                 << version_;
        return TEST_FAILED;
    }

Does this test need to be relaxed/modified for cross-version
replication?

From

"2013-11-21 10:08:29 3140 [Warning] WSREP: trx protocol version:
2 does not match certification protocol version: 3"

it looks like trx protocol 2 (of 5.5 node) is not compatible with
certification protocol 3 (of Galera 3 on PXC 5.6 node). Is this
right?
