Hi,

Taking this grammar piece as example:
'Type' name=QualifiedName ('extends' superType=[Type|QualifiedName])? 

To identify the superType, we can use a qualified names that contains one or more segments depending of the imports being used.

I would like to identify in a validation method how many segments are being used to identify the linked element, so I can infer if it is Single or Qualified name.

Could someone point me how can I do that?

thanks

like that - I don't know the exact name)
