The use cases are opposite to each other, e.g.:

- A.1 (464XLAT) is opposite to A.3 (SIIT-DC)
- A.3 (SIIT-DC) is opposite to A.1 (464XLAT)

...in the sense that an IPv4 packet traversing a 464XLAT CLAT and being
tranlated to IPv6 is sent by a local IPv4 app and is destined
for the public Internet, while an IPv4 packet traversing an SIIT-DC
gateway is sent from the public Internet and is destined for a local
IPv4 service.

No, probably not. We'll remove them, thanks!
