Crossreferencing graphiti resources from xtext grammar [message #1780642]

I have two ecore-models in the same project, lets call them grammar.ecore and diagram.ecore.

grammar.ecore has, amongst others, the following structure:

A
  -name:EString
B -> A
  -next:A
C -> A

while diagram.ecore has, amongst others, the following structure:

D -> A

Now I have in a grammar created in xtext with the grammar.ecore model above, and rules that result in grammar like

B foo {
  next bar;
}

B bar {
   next foo;
}

I also have a graphiti-based graphical editor where I create one D per file. These D's should be referencable from the grammar. The grammar- and diagram-instance-files are all in the same project in the same folder.

I'm aware that I must expand the scope but since I'm new to the whole topic I have no clue how to do this.

Thanks in advance!

Xtext can only have crross-reference to EMF models that are indexed.
