Summary of MathML Polyfill needs

[NSoiffer]

This is a list of all of the elements/attributes in MathML 4 marked as "not in MathML-Core" or "not-core". If the checkbox is checked, then a polyfill exists for the element/attribute. If the item is crossed out, then the Math WG has agreed that writing a polyfill for the element/attribute is not needed/encouraged.
