If you didn't own it on /1, then you can't use it. The intention is that an entity can mint tags on a date d when it was unassigned, if it became the assignee of the authority name _immediately_ after the continuous period of unassignment in which d falls. I still think that that is good as a logical definition. The question is whther there are good enough practical criteria for using it. Are you questioning whether there can be evidence that the name was unassigned immediately after the first entity ceased to be the assignee? The someone who picked it up on 2-7 would have to have evidence that it was unassigned. We're positing that such evidence may become available. >P.S. Are DNS records of who owned a domain throughout time kept >somewhere? Otherwise, one would have a difficult time proving that >they owned a certain domain ten years ago, or whatever. At whois.org there is something called a 'deleted domain search'. I suspect that someone, somewhere, has all the requisite information to make 'unassignment on date d' a verifiable predicate.
