Dear Chris, thanks for your feedback on the P3P specification. > 1. You specify only "text" as the type for the date.timezone field, > whereas this could be specified more precisely (like country code is). This is not the intent of the specification, and I'm sorry if you were mislead to assume there's no type constraint. After the date. table there is the precisation > All the fields in the date. type must be in the same format as those > in the most informative profile of the time standard ISO8601. (btw, because of your feedback I've changed "are" from the previous version of the spec into "must", to make this clearer). So, in essence it's a matter of taste whether to introduce a new type (like for Country), or using a more general type and specify a constraint on it. The current choice reflects the fact that eight types in date. now are compactly referenced to ISO8601, while making the type explicit would mean you've to create eight subtypes corresponding to ISO8601. Anyway, no semantic difference. > 2.

The timezone information can be inferred from user.home and/or user.business (from various fields, either city, or stateprov, or postalcode etc). In general, we have tried to keep the base data set to a minimum, avoiding fields that are not of common use (after all, new data schemas can be created too). However, if you feel that the ability to *directly* request a timezone can be of significant impact for many of today's sites, we'd appreciate some examples and use cases that could justify the introduction of a new timezone field. Again, thanks for your precious feedback, and feel free to reply with further questions and clarifications, until every doubt/problem you have is completely solved. All the best, -Massimo /---------------------------------------------------------------\ | Massimo Marchiori Room NE43-350 | | The World Wide Web Consortium (W3C) 545 Technology Square | | MIT Laboratory for Computer Science Cambridge, MA 02139, USA | | WWW: http://w3.org/People/Massimo Phone: +1 (617) 253 2442 | | Email: massimo@w3.org Fax: +1 (617) 258 5999 | \---------------------------------------------------------------/
