[news.eclipse.tools.emf] Re: Design Question: multiple viewers on one mo

[Ed Merks <merks@xxxxxxxxxx>]

Eike,

Yes, I agree.  I wouldn't do this as several models.  Rather I'd just 
specialize the item providers and a corresponding factory to alter the 
default behavior, like we did for XSDSemanticItemProviderAdapterFactory 
to show a logical structure as opposed to the physical structure...
