### Definition

Textual descriptions of math equations are included, whether in the alt attribute for image-based equations, using the alttext attribute for [MathML] equations, or by other means.

### Examples

### Explanation

The `describedMath`

value is used to indicate that a publication includes textual descriptions for math
equations.

Text descriptions can be provided, for example, using language-specific technologies like the
MathML `alttext`

attribute. They can also be provided using the HTML
`alt`

attribute when only images are used. The value is a human readable
equivalent.

This property is complementary to the `MathML`

and `latex`

properties, as the inclusion of either MathML- or
latex-formatted equations does not infer that text descriptions will be available.
