My sense in talking with various delegates is that the Danish text controversy is more of a wrinkle, if that. Delegates from South Africa, Mexico, Algeria hadn't even heard of it when I asked them about it late yesterday and early today; I haven't gotten any sense that these talks have come to a standstill or are in disarray.
The "text" isn't on the table, it's not a part of the talks. A member of the Mexico delegation, which is part of the so-called "compromise block" of states (including Switzerland and South Korea) trying to find common ground - told me yesterday that such rumors and stories of strife and conflict are fairly common during the first week of these negotiations.
There may indeed be a walkout at some point in the next few days. But it does appear, at least right now, there's far too much momentum behind this train for something like the "Danish text" to derail it.
