[gch@xxxxxxxxxxxxxx (Guillaume Chatelet)]

Hi Laurent,

I'm parsing text files (not XML) and generating models from those files. 
The resulting EMF model is not to be persisted so the EObject is not 
associated with a resource. Actually I saw I needed to add it to a 
resource before using EMF Compare. What would you recommend ? Create a 
dummy resource for any object I want to compare - with a valid URI ? Or 
rise an enhancement request to allow comparison with EObject not linked to 
a resource ?

Best regards,
Guillaume
