Sorry for the lack of updates on progress towards the P3P Last Call 
WD... well probably it wasn't the top thing any of you were worrying 
about, but none-the-less.... The WD is done except for sorting out some 
remaining issues with the new data schema. There is a draft of the data 
schema section at http://www.w3.org/P3P/2004/040826_base-data.html. 
Giles will be making a (hopefully) last round of changes to it in the 
coming week and then Rigo will be integrating it in and hopefully we 
will have a LC WD shortly there after. So, if you care about data 
schemas, now would be a really good time to pay attention. Here is how 
I think we are resolving the backwards compatibility issues with the 
new data schema:

- P3P 1.1 policies will use the P3P 1.0 format to reference data 
elements
- Custom data schemas will be provided by web sites in both the 1.0 and 
1.1 format.
   - We will provide translator scripts to go between these formats
   - the 1.1 format will be referenced using the extension mechanism as 
an optional
      extension so 1.0 user agents will ignore it
   - 1.1 user agents can ignore the 1.0 format and just read the 1.1 
format

This is all made possible by the fact that we now have translators 
going in both directions thanks to the hard work of Giles and Serge 
(although we are still doing some testing to make sure everything works 
as advertised).

Stay tuned....
