How to use the MathML Overscript Element: "mover"?

"mover" is the MathML Overscript Element that allows you to specify a base sub-element associated with an overscript sub-element.

The syntax for "mover" element is:

<mover> base overscript </mover>

"mover" element supports 2 useful attributes:

• "accent" - Specifies whether the overscript is drawn as an "accent" or as a limit. An accent is drawn in the same size as the base and closer to the base.
• "align" - Specifies whether the overscript is aligned left, center, or right. The default is "center".

Here is an example of using the "mover" element with accentunder="true".

<math><mover accent="true">
  <mrow><mi>x</mi><mo>+</mo><mi>y</mi><mo>+</mo><mi>z</mi></mrow>
  <mo>&#x23DE;</mo></mover></math>
    $\overbrace{x+y+z}$

Here is the same example with accentunder="false".

<math><mover accent="false">
  <mrow><mi>x</mi><mo>+</mo><mi>y</mi><mo>+</mo><mi>z</mi></mrow>
  <mo>&#x23DE;</mo></mover></math>
    $\overbrace{x+y+z}$
