In the case of MathML-content, I thought the lack of specification of, at least to my knowledge, the inverse-trigonometric functions have made Mathematica and Maple MathML-content behave inconsistently. Based on this experience (which I'd like to see one day written somewhere under an "interoperability" heading in the w3c.org/math pages), a new software being written should then declare something like: the inversed trigonometric functions shall behave the same as Maple, Mathematica (or OpenMath) ones. Hence my statement which was, sorry for that, sort of sketchy. I would surely not prevent new software to be written! Paul
