Wait... What?

There is a discussion paper posted on the web site of the Open GIS Consortium entitled "Uncertainty Markup Language (UnCertML)."

The Uncertainty Markup Language (UncertML) is an XML encoding for the transport and storage of information about uncertain quantities, with emphasis on quantitative representations based on probability theory.

I believe that this is a serious paper, but I have to admit I looked to make sure the publication date wasn't April 1.

I'm just not sure how much of this I should read...
