I don't know about "we". What I would be proposing for HTML5 is just the following list of elements: math, mrow, mfrac, msqrt, mroot, mstyle, merror, mpadded, mphantom, mfenced, menclose, msub, msup, msubsup, munder, mover, munderover, mmultiscripts, mtable, mlabeledtr, mtr, mtd, maction ...and of those only <math> came up at in the top 1000 elements in my search of elements on about one billion pages. According to that same research, <math> is, on the Web, less frequent than the following elements: <m>, <e>, <rem>, <tab>, <yr>, <prohibits>, <your>, <lable>, <text-spez>, etc. It was present on less than 0.002% of the pages the research covered. (To give an idea of scale, <h8> is used on more than 0.003%, so if we avoid <math> because of this, we should probably introduce <h7> and <h8> into HTML, since we're saying that's an important enough level to worry about.) Now, of course, it could be that those 0.002% of pages are all hugely important and that we'll break the Web in adding this feature. We can't know until we've tried. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
