Jörg,
I don't think Eclipse generally supports dynamic changes to the locale.
It would generally be necessary to exit and start Eclipse with a
different -nl argument to ensure that properties from the appropriate
*.properties files are loaded consistently throughout the IDE. That's
because lookups tend to be cached based on the locale at the time of
first lookup...

Jörg,
I see. I can imagine having a different instance being edited for each
language; that would be relatively simple I guess. The alternative
starts to sound more like each property should be a EMap from language
code to the actual value the property has for that language, but that's
obviously modifying the metamodel. I can't think of much else that
doesn't modify the metamodel in some way...

Hi, Jörg,
This sounds similar to what the MDT UML2 component's editor for UML models
does, to localize the names of model elements in *.properties files.
The keys of these properties are constructed from the qualified names of the
elements. I imagine that extending this syntax with, for example, an
attribute name could be a simple way of localizing attribute values.
Note also that the UUIDs generated by EMF are valid keys in *.properties
files, if you are using UUIDs.
Take a look at the org.eclipse.uml2.uml.edit plug-in to see how its item
label providers access localized text.
HTH,
Christian
