I need to find out if I can disclose the details on this one. If I can it will be in the doc. I beleive its a simple IA5String. Again, these will be listed in the public OID doc. Hope this helps.
OID extension contains country, zip, date of birth, and gender.
This data is masked to prevent misuse or abuse by third parties. I was told that I'd have to contact my sales rep and enter some sort of non-disclosure agreement to learn how to unmask the data. The designated sales rep has not responded. Verisign fails to give an sufficient answer.
