StateProv as Physical Contact?

Hi,

I have been working with the P3P specification and was wondering why
StateProv is listed as being Physical Contact when Country and Postal Code
are Demographic.

It would seem that "reading" a postal code would allow the data collector to
more accurately identify a physical person than knowing their State or
Province. In any case, without a name, knowing either piece of information
is not helpful for locating the person.

As it stands, then, a site has to declare a PII related category (Physical)
when collecting stateprov and not when collecting postal code. It would be
more consistent to have postal code, stateprov and country all in the same
demographic category.

Thanks!
