RE: R41 in draft-ietf-v6ops-cpe-simple-security-07

Hi,

Thank you for the clarification, I now see the intent. Ok for that as is.

While speaking, in 3.4 I-D says:"It remains to be seen whether the Internet Gateway Device profile of the Universal Plug And Play protocol will be extended for IPv6.". For me that sounds like there would be possibility for UPnP not being extended to IPv6, which is definitely not the case as work is currently being done to extend UPnP with IPv6. As the work is in progress, at this point the document could say instead:"Internet Gateway Device profile of the Universal Plug And Play protocol is being extended for IPv6."

I agree with Barbara that second sentence of R41 is not appropriate. What would be the possible replacement for the MUST, if that is taken as compromise approach?

Best regards,

	Teemu
