I still feel more comfortable with the top level of the TZIDs. The most clear example for me is the situation with Russia: at the one hand you have Europe/Moscow which is clearly felt to be in Europe, at the other hand there is e.g. Asia/Kamchatka, which should not be shown in Europe at all. So, at the very least, the data of CLDR and the TZID top level needs to be combined to avoid duplicate entries in a UI. Peter. Mark Davis wrote:
I would tend to agree on the NSEW split that the UN has, for some cases, in particular for Europe. Looking at http://www.unicode.org/cldr/data/diff/supplemental/supplemental.html, for example, they put the UK and Latvia in Northern Europe, while some might put the UK in Western and Latvia in Eastern.
On the other hand, where someone did want to have a more manageable hierarchy of shorter lists in their UI, it might be a reasonable choice to start with the UN list. There is nothing to prevent a UI from using mutiple territory containments. For example, one might list Turkey under both Asia and Europe, so that it would appear in both lists.

I'm not saying that one should necessarily use all the levels of
containment. It depends on other aspects of the UI. The 2nd level of the UN tree is actually reasonably close to the top level TZID arrangement.
UN:
Europe [150] Eastern Europe [151] Northern Europe [154] Southern Europe [039] Western Europe [155]
I note that you are just copying the UN data, but that split into North, South, East, and West Europe bears almost no relation to anything that anyone uses in reality.
