Tantek,

I'm going through your suggestions one by one. I'm creating one slide
each for discussion in next week's meeting. I'll write email for those I
don't understand or otherwise need to discuss.

The PREF parameter was present in vCard 3.0 and 2.1. It is very widely
used. One of the first features requested for 4.0 was the ability to
"quantify" preference. The value range was chosen with input from OMA
and resulted in clear WG consensus.
