In section 4.4.1.1.3 the last example is an example of 'pi', where 'pi' is expressed as a symbol. This notation is not in the spirit of content mathml, as 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/> Since the grammar does not say what type="constant" means, using π is not forbidden (for all we know, the author's number system could be π ρ σ). However, I don't see it that this notation should be promoted by listing it in the specification. For completeness, this is what the paragraph I'm referring to looks like: 4.4.1.1.3 Examples <cn type="real"> 12345.7 </cn> <cn type="integer"> 12345 </cn> <cn type="integer" base="16"> AB3 </cn> <cn type="rational"> 12342 <sep/> 2342342 </cn> <cn type="complex-cartesian"> 12.3 <sep/> 5 </cn> <cn type="complex-polar"> 2 <sep/> 3.1415 </cn> <cn type="constant"> π </cn> Kind regards, Michael McCarthy.
