It is the goal of this group (per  the charter) to look at what  
uncertainty information needs to be captured, e.g. is a numerical value  
attached to a sentence/proposition/... sufficient?  Under what  
circumstances is a numerical value sufficient?  When it is not  
sufficient, what else is needed?

While we can make "obvious" suggestions (should such suggestions become  
obvious), it is not within our charter to specify syntax.

P.S. If terminology used in other standards (W3C or otherwise) are  
useful in expressing our concepts, we should not invent new terms where  
none are needed.  On the other hand, we should not feel compelled to  
use terms we feel are inadequate for our needs.
