I'm trying to get a handle on Mathematica's XML capabilities. I'm finding a few things to be a bit confusing. One of these is where the http://www.wolfram.com/XML/DTD/2001/NBMLwMathML.dtd really is. Another point of confusion is how exactly the rendering in the browser is expected to take place. If needs be, I can spin up my own CSS. Does Mathematica provide CSS for MathML or NBML? I've character mentioned entity references before, but I still haven't found an answer. What I've found here seems inconsistent with what Mathematica chose for the character entity reference for an imaginary number: http://www.bitjungle.com/~isoent/ This is what Mathematica produced for a complex number: <b><p class="Input"><math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow> <mrow> <mi>cpx</mi> <mtext> </mtext> <mo>=</mo> <mtext> </mtext> <mrow> <mn>1066</mn> <mtext> </mtext> <mo>+</mo> <mtext> </mtext> <mrow> <mn>42</mn> <mo>⁢</mo> <mi>ⅈ</mi> </mrow> </mrow> </mrow> <mo>;</mo> </mrow> </math></p></b> If I understand the http://www.bitjungle.com/~isoent/ent.xml, the imaginary number symbol should be ࠿ which is a black letter capital 'I'. That doesn't seem correct to me. I'm currently stumbling around in here looking for a possible clue as to what I should expect: http://www.physiome.org.nz/Docs/web-tech/specs/mathML20/chapter3.html Has anybody worked with this? STH
