My question is, where should > it go? Even with latex, punctuation of displayed equations can be tricky to get right, they tend (depending on how you mark it up) to either be too close to the mathematics, or adversely affect the positioning of the mathematics, or ... If you are using presentation mathml I think it's OK to use an <mtext>.</mtext> even though structually the mathematics is part of the sentence so one might argue that the xml structure ought to reflect that and have the . outside the <math>. It's possible to do that as well of course, something like <div class="displaymath"><math> ...</math><span>.</span></div> with the math here being "inline" but set in displaystyle (as far as mathml is concerned) but positioned centrally using css, and similarly the punctuation being placed within the display block but after the mathematics. This keeps the math element clear of document-level sentence punctuation, which might be especially useful if you are using content mathml. DavidReceived on Friday, 26 January 2007 12:08:13 GMT
