Hi,
You are right. Currently the contribution system expects you to know the
ID of the element but for 4.1 I plan to improve it in a way that you can
use XPath expressions one could then contribute to the
MApplication-Element through "/MApplication", ... .
In 4.0 you can use a Processor to generically identify the root element
to contribute a command and do much more fancy contributions (e.g. based
upon a user credential, ...).
If you are not sure how this looks like you can take a look at my
Live-ModelTooling integration which does exactly what you asking for here.
The source is available in:
e4/org.eclipse.e4.tools/bundles/org.eclipse.e4.tools.emf.liv eeditor and
the thing you are interested in is the:
* ModelProcessor
* plugin.xml
