I have renamed the related List label by following the below steps
Setup --> Translation Workbench --> Override.
Select the filter criteria:
Package {!Name of the Installed Package}
Language "English"
Setup Component "Custom Field"
Object {!Name of the Object}
Aspect "Related List Label"
Now i want to retrieve this from pacakge.xml . But not able to get the related List Label. Can any one please help me to retrieve the changes for renaming the related list
