Oooh, does it?? That is, where did those IEXT(I(math:whatevers)) get 
their semantic restrictions from? Can a datatype impose some extra 
semantic conditions on some *properties* as well as on the datatyped 
literals ?? That's a more generous notion of datatype than we have 
been considering up to now. .

I didn't put anything like that in the MT, but maybe I should have 
done. In fact I like this idea.

Where are the math: thingies defined? (URI??)
