What is the purpose of the LangVar in the additional fields for registrars?

[boatcoder]

I have this definition:

$additionaldomainfields[".xxx"][] = array(
   "Name" => "ICM Registry Membership Number",
   "Description" => "To purchase a .XXX domain, you must have an ICM membership.  You can apply for one <a href='http://www.icmregistry.com/members/'>here.</a>",
   "LangVar" => "icmMembershipNumber",
   "Type" => "text",
   "Size" => 64,
   "Required" => false,
);

 

And I get this in the params:

       "additionalfields": {
           "ICM Registry Membership Number": "1234567890"
       }

 

Why don't I get the LangVar name instead of the human readable name?

Hi,

The langvar enables you to translate the field label on the shopping cart pages using language override files. It will override the "Name" value.
