I am attempting to write a program which will generate MathML from algebraic expressions. The problem is when working on complex expressions, when is the type= information needed. For example, for z = (1,2) <declare type="complex-cartesian"> <ci>z</ci> <cn>1</cn> <sep/> <cn>2</cn> </declare> Is this correct or should the type be repeated in the first <cn> ? and for z = (x,y) <declare type="complex-cartesian"> <ci>z</ci> <ci>x</ci> <sep/> <ci>y</ci> </declare> Here if I repeated the type in the <ci> for x it would imply that x is complex which is not what I want. Please point me to some examples, as I can't find these points answered in the definition statement.
