i fully agree with you as zero-lengthed EA-bits is a naturally possible
case of MAP. however, to my understanding, even in this case the Figure 7
of MAP addressing architecture is still appliable and therefore it implies
PSID length also equals to zero. this is the real meaning of 1:1 that is a
natural case possibly occurs rather than a "mode" - mode is a sort of
preset configuration. and further, it is not necessary to disable NAT44 in
such EA-null/PSID-null cases at CE.

this definitely makes the MAP spec clear. if necessary, including this
special case in the MAP draft or in the MAP deployment draft, mentioning
its usage, is what i support unless we discover any other flaws regarding
this.

cheers,
maoke
