I am still lerning Xtext/Xbase and investigated the source of Xbase.xtext.
I found the following expression "feature=[types::JvmIdentifiableElement|OpMulti]" and want to know what is it's semantic ?
ObMulti is only terminal rule. Where does the JvmIdentifiableElement comes from when parsing or linking an Xbase XExpression ? How is it created ?

it means

- reference a JvmIdentifiableElement
- parse a OpMulti

so in general:

Thanks, that means the linking happens in the ScopeProvider ?

Linking happens in the ILinikingService, which usually is the DefaultLinkingService. The service uses the IScopeProvider to resolve the parsed text to a named element from the scope.
