Dear all,

I think this initial draft is a good starting point. But there are a  
few major things, i am wondering about:

a) what about using interfaces as Victor proposed in [1]?
b) did we choose one of the two possibilities for the API already  
(specific vs. common)? AFAIK only a few of us discussed these two  
different approaches [2].
c) the datatypes are only "placeholder" for the finite datatypes, or?  
Because some of them do not fit their purpose i guess.
d) as Victor already pointed out, WebIDL is in scope of our group, so  
we should bring this discussion to an end and use it...

I think we have to discuss this draft more closely in todays telecon.

Best,
Florian
