Hi Jose,

I left out DIAL v2 since we need to get v1 further along the 
Recommendation track first. Of course, we could just do v2 and get 
on with including SVG, SMIL and XBL if that is what the working 
group desires, but with the current plan, we should move v1 to Last 
Call later this year, and enter Candidate Recommendation early next 
year. Let's see what people think. If necessary I could always set 
up an online questionnaire -- we can discuss this in next week's 
call.

Thanks for offering to help with the policy work. I think the first 
step will be a document covering use cases and requirements. With 
regards to the delivery context ontology, I am keen for us to 
publish a first working draft as soon as practical. We can then 
update it as necessary as we head towards a last call. Let's use 
next week's call to see see where we are on this.

Best regards,

  Dave Raggett <dsr@w3.org> http://www.w3.org/People/Raggett
