Jeremy,

Your list of requirements mean that I can't help but support BP 2's 
removal. However, I am sorry to say that this issue was not addressed in 
DWBP. The nearest advice would be DWBP 3, provide structural metadata 
(which refers to CSVW among other things), and BP 13 which is about 
locale neutral data (separate currency and value, rather than give a 
value as "£12.50" or whatever).

I know that Dave Raggett (in cc) has been looking at the issue of UoM 
for WoT. The QUDT vocab is too heavy weight for his needs. He may have 
something else to add to this.

That said, it does seem to me that SDW BP2 overlaps somewhat with BP1 
(which talks about CRS ad TRS as well) so I see why BP2 can go without 
too much loss.
