I agree the mime-type of the content of a semantics element is to be 
disjoint of the mime-type of the document but don't you think that the 
type of semantics element (call it a label, an annotation, or...) is 
close to a mime-type and further than a language ?

A mime-type describes possible software operation whereas a language 
can only be made acceptable or not by a human.
I think it is fair for a computer algebra system to describe through 
mime-types that it suports a set of symbols...
