### Definition

Identifies that mathematical equations and formulas are encoded in [MathML].

### Examples

### Explanation

The `MathML`

value is used to indicate that the MathML markup language has been used to encode the
mathematical equations. For Web-based formats like EPUB, Presentational MathML is used to
encode the content as it can be displayed in a growing number of reading systems and
browsers.

Although Presentational MathML often lacks important semantic information that is only available in Content MathML, it is supported by assistive technologies which allow users to more easily navigate and understand the content.

The `MathML`

value is often paired with the describedMath
value when fallback descriptions are provided.

See the MathML knowledge base page for more information.
