For Håkon 's proposal, to get list of strings to display for "en-US", I'll have to check groups for "en-US", then (if not present) "en" and then fallback to some other language. Or should I merge list of strings from "en" and "en-US"? This already introduces ambiguity and tools will break it almost for sure trying to save space. 

Compare this to: get list of strings by simply enumerating <items>. For each of them walk <name> and <text> tags and choose one with best language. This will be one pass through <extensions>, without ambiguity.

I do not worry about repetition and depth level, if it is easily readable, which it is in this case.

Thanks,
Sergey

Eww no, way to laconic.

I am aware this may be too many levels deep, but I'd like to suggest:


<extensions>
	<group>
		<set lang="en">
			EU Greeting
			<item>
				Message
				<value>Hello!</value>
			</item>
			<item>
				Date
				<value>2010-06-01</value>
			</item>
		</set>

		<set lang="nl">
		EU Groet
			<item>
				Bericht
				<value>Hallo!</value>
			</item>
			<item>
				Datum
				<value>2010-06-01</value>
			</item>
		</set>

		<set lang="fr">
			EU Salut
			<item>
				Message
				<value>Bonjour!</value>
			</item>
			<item>
				Date
				<value>2010-06-01</value>
			</item>
		</set>
	</group>

</extensions>
