accessing additional domain info

[mice-pace]

Does the extra info stored as a result of additionaldomainfields.php act like a normal parameter or some kind of subset?

 

I guess what i'm asking is, as an example would i access it like this:

 

$registrantCountryCallCode = $params["additionaldomainfields"]["CountryCode"];

 

or like this:

 

$registrantCountryCallCode = $params["CountryCode"];
