WIRIS flavor

The MathML Recommendation leaves room to interpretation in some sections. WIRIS editor has made some decisions about that. So some images differ from the W3C sample, but are still correct. For example:

• WIRIS editor uses sans-serif font by default because it's better for the web. See Why Sans-Serif?.

• To better follow the MathML Recommendation, we suggest you to set the parameters defaultStretchy=true and display=inline.
