Mozilla MathML Status

An overview of the MathML 3 elements/attributes - excluding deprecated ones - and the current status of the native support. References to MathML 3 are given. The sections are marked with their current status: supported, in progress, and not currently supported. Sections related to semantics/content MathML or irrelevant features are left blank or not listed at all. If only the main features of an element are implemented then its section is marked as supported but details of unsupported attributes are specified below.
