Simple commutative diagrams could be built using tables. To make them 
look better one could adjust the height of certain rows as well as the 
width of certain columns. This would work good because a stretchy 
operator (for example an arrow) stretches to the size of the mtd if it 
is it is the sole subexpression of the mtd.

Is there another way to achieve the same in MathML? Anyway, for 
commutative diagrams, one perhaps better uses SVG (or even better, 
MathML in SVG).
