You were right, I totally forgot to load the KM3 metamodel itself.
However there is still a problem with the following new code:
<target name="inject">
<am3.loadModel modelHandler="EMF" name="KM3"
nsUri="http://www.eclipse.org/gmt/2005/KM3"
metamodel="MOF" />
<am3.loadModel modelHandler="EMF" name="${model}"
path="${model}.km3" metamodel="KM3">
<injector name="ebnf">
<param name="name" value="KM3" />
</injector>
</am3.loadModel>
<am3.saveModel model="${model}" path="${model}.ecore" />
</target>
Unlike Ecore files produced by the Eclipse plugin, the resulting Ecore file
does not use the namespace http://www.eclipse.org/emf/2002/Ecore and
elements like eClass, eAttribute but the KM3 namespace
(http://www.eclipse.org/gmt/2005/KM3) and different elements like Metamodel
and Contents, thus making it incompatible with other EMF tools.
I'm sure that there is a simple way of fixing this problem, maybe adding
another injector parameter... Sorry, I'm a bit newbie with these tools.
Regards.

Hi Lorenzo,
After the injection of your .km3 file, you get a KM3 model (M1 level),
conforming to the KM3 metamodel (M2 level), itself conforming to Ecore
(M3 level). If you want to get a metamodel from the KM3 model, you have
to "promote" this model. You can do this with the transformation KM32Ecore.
Regards,
Mikael
