box (Box Function)

This element specifies the box function, which is used to group components of an equation. A boxed object can (for example) serve as an operator emulator with or without an alignment point, serve as a line break point, have associated argSz, or be grouped such as not to allow line breaks within.

The equation uses a box around the double equal sign.

[Example: Its XML representation is as follows:

<m:r>
<m:t>a</m:t>
</m:r>

<m:box>
<m:boxPr>
<m:opEmu   m:val="on"/>
<m:aln/>
</m:boxPr>

<m:e>
<m:r>
<m:t>==</m:t>
</m:r>
</m:e>
</m:box>

<m:r>
<m:t>b</m:t>
</m:r>
