Use the <equation-inline> element to represent an equation that is presented inline within a paragraph or similar context. Inline equations are not intended to be numbered.

When an <equation-inline> element has multiple direct child elements, each child represents an alternative form of the equation. Processors are free to choose the form or forms that they use in deliverables. For example, if there is both an image and MathML markup, an HTML-generating processor could output both the image reference and the MathML with appropriate HTML @class or @id values to enable dynamic showing or hiding of one form or the other based on browser capability.
