Comment:
First, Skinsmoke, you need to AGF. I have not been trying to convey a biased picture of the guidelines, as your comment "very selective" seems to suggest. While browsing the page, I may have missed something, and skipped parts that didn't seem to apply at first glance, but if so, it is an honest mistake, and I resent comments suggesting anything else.
Second, the guidelines seem to use the words "normally" and "often" and "sometimes". That doesn't seem very binding.
Third, I don't remember being in a discussion last week where the "European pattern of disambiguating by comma" argument was used. Which one of the supporters above are you referring to? It surely isn't me, because I strongly disagree. This "City, State" naming convention is North American, at least in my world.
On the subject matter, I can't imagine that any Dane in his right mind would refer to the Danish city of Hatting as "Hatting, Danmark". Likewise, I don't think any yodler would refer to the Austrian city of Hatting as "Hatting, Österreich". Ergo: both cities are named Hatting. Also, if you check the da.wiki names for the cities dabbed by the municipality name (in the other RM), you'll see that they're all having the dab in parentheses. So, "[a]ny specific national convention takes precedence though", right? Ergo: the dab should be in parentheses.
In any case, if there really are binding rules to your interpretation, I think they should indeed be changed.
