Example
In the following example, a block equation uses MathML as its content:
<p>A block equation using MathML:</p>
<equation-block>
<mathml>
<m:math>
<m:semantics>
<m:mrow>
<m:msqrt>
<m:mrow>
<m:msup>
<m:mi>a</m:mi>
<m:mn>2</m:mn>
</m:msup>
<m:mo>+</m:mo><m:msup>
<m:mi>b</m:mi>
<m:mn>2</m:mn>
</m:msup>
</m:mrow>
</m:msqrt>
</m:mrow>
</m:semantics>
</m:math>
</mathml>
</equation-block>
In the following example, a block equation uses an image as its content:
<p>A block equation using an image:</p>
<equation-block>
<image keyref="equation-image-01">
<alt>a squared plus b squared.</alt>
</image>
</equation-block>
In the following example, the block equation contains two alternative forms of the same
equation:<equation-block>
<image keyref="equation-image-01">
<alt>a squared plus b squared.</alt>
</image>
<mathml>

<m:mn>2</m:mn>
</m:msup>
<m:mo>+</m:mo><m:msup>
<m:mi>b</m:mi>
<m:mn>2</m:mn>
</m:msup>
