1) if the intention is to refer to a symbol called 'pi', then the appropriate mechanism is to use the <csymbol/> element instead of using the <cn/> element 2) this constant is already defined as <pi/> I think that's probably true (now). The example dates from mathml 1 which didn't have either <csymbol> or <pi/>. So as you commented, it's definitely still legal but I think almost all the uses for which <cn type="constant" was intended could better be done with the newer MathML2 Content elements such as <pi/> or with <csymbol>. so this usage probably should be deprecated. (Now is a good time to raise such issues as we are working on a draft of mathml2 2nd edition....) Since the grammar does not say what type="constant" means, The grammar doesn't, but 4.3.2.9 on the type attribute does say more about this (and would need changing if your suggestion to deprecate this usage was accepted).
