The MathML(expr, opts) function translates the Maple expression expr to MathML text.

The output=style option, where style is one of content, presentation, or parallel, can be included. If the output=content option is provided, then content-only MathML is produced.  If the output=presentation option is provided, then presentation-only MathML is produced.  Otherwise, parallel (both content and export) MathML is produced as the default.  See the MathML package help page for a description of the parallel, content-only and presentation-only encodings, and for additional information about MathML.

The filename=fn option is used to direct the output to the file with name fn, where fn is a string or symbol.  Otherwise, the default output stream is used. If you are using the MathML command interactively, the default output stream is the terminal screen.

The function MathML produces MathML code as a side-effect and returns NULL as the function value. Therefore, the ditto commands (% and %%) do not recall the output from the MathML command.

The command with(codegen,MathML) allows the use of the abbreviated form of this command.
