As you know, the Dairy Farmers of Canada have also put forward other options beyond article 28. In fact, you referred to one a little earlier, the harmonization to 90% protein concentration.
To address what you said about Canada not using article 28 in the past, what I said was that since the agriculture negotiations began in 2000, we haven't used it. We have used it in the past, mostly for technical reasons.
As far as the use of article 28 by other countries is concerned, if you'd like, I'll turn it over to my colleagues from the Department of Finance, but my understanding is that since the Uruguay Round, the use of article 28 has been rather limited, and mostly for technical reasons, for example, EU enlargement, etc.
Would you like us to elaborate on the use that other countries have made of article 28?
