If you run your private wiki you can allow that users can input formulae
in different input formats.

attribute

- pmml
- Presentation MathML
- ascii
- ASCIIMath

For example asciimath input can be entered via

`<math type="ascii">d/dxf(x)=lim_{h->0}(f(x+h)-f(x))/h</math>`

and looks like**Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle d/dxf(x)=lim_{h->0}(f(x+h)-f(x))/h}**
