Clarify the meaning of "value." Which of these would fit: 2x+1, 2x, x, 2/3, sqrt(3), 4. IMHO, a "value" is identical to an expression since once the value of all variables is known, an expression can be simplified to a constant, which is always considered a value. Whether the value of the expression is always the same or depends on the value of some variables seems irrelevant to me. > > Wouldn't MathML be > > better-suited for that? > > for expressions yes. for simple numeric values i > believe the expression is > (no pun intended), swatting a fly with a > sledgehammer. > > > (Yes, I know about the "pain to hand-author" > > argument.

I think you're saying that MathML would be too cumbersome or unwieldy for this purpose. As far as I can tell, marking up a number (or any expression) in MathML would not be more difficult or annoying than using a <num> element. Assuming that a specialized editor is being used (not just a text editor), a <num> element would be used by highlighting some text, and clicking a "number" button. Using MathML, text would be highlighted, and on a Math menu, a "standard math expression" option would be clicked. Not any extra work for authors, but it would be much more flexible. Is there any *disadvantage* to using MathML this way? -Jeremy Rand PS: Sorry if any non-ASCII characters get screwed up in this message; Yahoo!'s webmail won't let me send in Unicode.Received on Monday, 3 November 2003 14:56:50 UTC
