I remark without prejudice that the LaTeX encoding isn't attempting to capture semantics, merely layout glyphs. If you are content with the LaTeX encoding, why not use presentation MathML to achieve the same result? --Robert From: www-math-request@w3.org [mailto:www-math-request@w3.org] On Behalf Of JB Collins Sent: Tuesday, November 04, 2008 3:06 PM To: David Carlisle Cc: www-math@w3.org Subject: Re: Volume integrals in Content MathML p.s. Alternate differential volume element representations are (in LaTeX) $d^3{\bf r}, d\tau, dV$. For usage context, see for example: Gauss's Theorem, Chap1, §1.1, Math Methods for Physicists, 2ed, by G. Arfken (1970), and corresponding exercises. Also Chap 5, titled "Vector Integration", in Schaum's Outline of "Vector Analysis" by M. R. Spiegel (1959) It would be useful to have a way to abstractly refer, in a basis free manner, to curves, surfaces, volumes, etc., over which integrals are to be evaluated.
