Question about Language Key in OrgModeler 4.1 SP2

Hi Expert,

I notice that in most XML files especially for Data Elements (Both Org Source and Organization Structure in Scenario) For Example:

createorgunitviewdataelement.xml

createpositionviewdataelement.xml

IT1000JobDataElement.xml

IT1000KeyPositionDataElement.xml

IT1000OrgUnitDataElement.xml

IT1000OrgUnitSearchDataElement.xml

IT1000OrgUnitSearchDataElement_NoAuthentication.xml

IT1000PositionDataElement.xml

IT1000PositionSearchDataElement.xml

IT1000QualificationDataElement.xml

SAPEmployeeDataElement.xml

,

, there is a tag LANGU='[Lang LangKey]'

My Questions is:

Where can I re-define the Language Key parameter (Lang Langkey) in the application instead of change it in all related XML files manually?

(It seems default language key is 'E' (English))

Thank you very much for your help.

Chairith.
