It seems that X-Trans-Id doesn't comply to Swift implementation nor OpenStack Object Storage API v1 which defined the header type as csapi:uuid.

1. RGW via FCGI frontend:
$ curl -i ${publicURL} -X HEAD -H "X-Auth-Token: $token"

What Tempest's tests expect is:

            elif key == 'x-trans-id' and \
                not re.match("^tx[0-9a-f]{21}-[0-9a-f]{10}.*", value):
                return InvalidFormat(key, value)

The currently used presentation format of X-Trans-Id causes early failure of many tests and thus could hide more important issues.
