> David and Donald,
> Thank you for your comments on the postal element in the P3P
> specification and its relationship to ECML [1], [2]. The P3P specification
> working group reviewed your requests (and followed up via
> a telephone conversation with David), and we have decided to
> leave the postal field the way it currently is.
> The P3P spec on which the ECML data schema was based
> (from about a year and a half ago), included a base data
> schema in whcih all of the elements of the data schema were
> typed. This data schema was designed to be used with a P3P
> user agent that would automatically send data
> elements in response to data requests in P3P policies. Since
> then we have removed automatic data transfer from P3P, and
> we have removed typing from the base data schema. Part of
> our motivation to remove typing was to address some I18N
> issues, in which it was difficult to type some of our fields in
> a way that was not specific to a specifc country. We have
> basically switched to a schema that is designed to represent
> data conceptually, in hierarchical structures, without saying
> anything about the actual form the data might take. While
> there may in fact be a one-to-one mapping between many of
> our base data elements and elements in a typical HTML
> form, we do not expect this to always be the case. For example,
> we expect some forms to have multiple elements that all map
> to the same element in the P3P base data schema. This
> would likely be the case for the street address component
> of the postal address.
> We expect more work to be done by other groups (ECML,
> XML Forms, etc.) in figuring out how to integrate P3P with
> HTML/XML forms. We expect that what ever convention is
> developed will reference the P3P base data schema for
> privacy purposes, but a more specific schema that includes
> type information, for form-filling purposes. We can imagine a
> number of different ways this might be done, but that is beyond
> the scope of our work.
