Ole,
As I suggested earlier, you could simply say that the WHOLE
ARCHITECTURE is based on IPv4-IPv6 address embedding and because
setting EA bits=0 changes this very basic assumption, it's not
allowed/supported in MAP.

I got a general question. The current MAP support 1:1 mode where EA-bit is a
full 32-bit address. Why we want to reinvent a wheel to create another 1:1
mode? The only difference is to move the configuration from DHCP server to
rules in the BR. Did I miss something?
just the opposite.

I am not asking whether MAP supports 1:1 mode with no EA bits or not. I am

Where can I get the formal definition of 1:1 mode? My understanding of 1:1
refers to one public IPv4 address per subscriber but you refer very
specific to decoupling IPv4 and IPv6 addresses.
Before MAP was accepted as WG item, MAP was proposed to embed IPv4 address
information (EA bits 0)
