[news.eclipse.tools.emf] Re: Does ID property have to be unique in the w

[koloale <koloale@xxxxxxxxx>]

Of course it XML semantics if id property of xsd:idref type. But when I 
generate Ecore model from Java classes, my id property has no connection 
with idref schema type. So is it feasible to deduce type from eReference 
and search object with given id among only objects wthis correspomding 
of reference type? Besides, all information for that is available.
