Thanks for the explanation - got it.  Sounds good to remove the statements.  Other than that, the document looks good to me.

Hi Hemant,

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) 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!
