Use the EMF Content Parser extension point to resolve content types
I am currently working on the BPMN 2.0 metamodel, using EMF to generate a Java model and a basic editor to edit .bpmn files.
At the same time, I maintain the BPMN modeler.
Everything was running smoothly until I tried to self host with both projects in my workspace. I saw my BPMN modeler trying to open BPMN2 files, and vice-versa.

Now how do I use this with EMF ? The solution is quite simple:
Problem solved!
PS: While playing with content types, I noticed the schema folder for the plugin org.eclipse.core.contenttype is missing! I opened 308126 to follow up.
