[news.eclipse.modeling.tmf] Re: How to make a reference like model::some

[Knut Wannheden <knut.wannheden@xxxxxxxxxx>]

Hi Eckle,

Using Xtext 0.7.2 I could not confirm this. I declared my grammar as follows 
and all I got was unresolved reference errors as I hadn't defined the scoping 
semantics:

Model :
    'model' package=[ecore::EPackage|STRING] ('as' alias=ID)?
    (refs+=UseMyRef)*;
UseMyRef :
    'using' name=ID 'for' modelElement=ModelElementRef;
ModelElementRef :
    (model=[Model] '::')? classifier=[ecore::EClassifier];

What version of Xtext are you using?

Hope that helps,
