The mathml syntax should -ideally- be the same as in latex
Although of course not everything can be implemented: wims_mathml is 1 MB … latex is somewhat larger (…)
The latex syntax is \mathcal{} : equal to wims_mathml.
So \mathcal A is sloppy latex : there is no relax in wims_mathml. If such an error is flagged , due to unsupported syntax, we will switch to image mode for this tex-string. I don’t know why the rest of following correct latex is not presented in mathml ?
The experimental \cal in mathml is for 1 char only yylval=wims_mathml_copy3("&",yytext+5,"scr;")
yytext+5 is just a single char.
