FWIW, I did a quick test with Maple (the only interesting target I have at hand) and both <math><apply><ci>round</ci><cn>3.5</cn></apply></math> and <math><apply><csymbol>round</csymbol><cn>3.5</cn></apply></math> get interpreted as Maple's function 'round' applied to 3.5. I suspect (in this case and similar ones) Maple just takes whatever cdata the first child of apply has and uses it as a function name. If it happens to coincide with a function Maple knows, then it will work. (In some other cases, like <ci>plus</ci>, Maple clearly does know what function it is actually meant, since it converts to the standard + sign) eduardo On Nov 5, 2012, at 12:11 PM, David Carlisle wrote: > On 05/11/2012 14:38, Daniel Marques wrote: >> Hi, > >> Another option could be, <ci>round</ci> which is more general and allows a >> free interpretation by the posterior usage of the content MathML. >> > > > Or better I think <csymbol>round</csymbol> as using csymbol rather than ci gives the hint that it is referencing some externally defined function (rather than a local variable in an expression within the page) just by not giving a cd or definitionURL attribute you are declining the opportunity of referencing a particular definition. > > David > > > > ________________________________________________________________________ > The Numerical Algorithms Group Ltd is a company registered in England > and Wales with company number 1249803.
