This element specifies the alignment property on the box function. It is utilized only when the box is designated as an operator emulator. When true, this operator emulator serves as an alignment point; that is, designated alignment points in other equations can be aligned with it. [Example: For example, the following equation uses the operator emulator as an alignment point. .

Its XML representation is as follows:

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

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

Attributes

Description

val (value)

Specifies a binary value for the property defined by the parent XML element.

A value of on specifies that the property shall be explicitly applied. This is the default value for this attribute, and is implied when the parent element is present.

A value of off specifies that the property shall be explicitly turned off. This is implied when the parent element is not present.

The possible values for this attribute are defined by the ST_OnOff simple type (§7.1.3.9).
