There's nothing "simple" about references anymore, and nothing really "generic"
either, just references that we extract with rules or without.

Passing the "type" to extractReferencesFromList did not seem needed and looked
weird. Also, renamed that method to parseReferences to avoid ending up with too
many extractReferences functions.
