22.1.2.80 opEmu (Operator Emulator)
This element specifies the Operator Emulator property on box. When 1 or true, the box and its contents behave as a single operator and inherit the properties of an operator. This means, for example, that the character can serve as a point for a line break and can be aligned to other operators. (For more details on the properties of an operator, see Unicode Technical Report #25, §3.2.2 and §3.2.3, and Unicode Technical Note #28.) Operator Emulators are often used when one or more glyphs combine to form an operator, such as .
When the element is absent, the default value of the property is 0 meaning that this property is not applied.
When the element is present and the val attribute is absent, the default of the val attribute is 1 meaning that this property is applied.
[Example: The following equation uses an Operator Emulator:
Its XML representation is as follows:
<m:r>
<m:t>a</m:t>
</m:r>
<m:box>
<m:boxPr>
<m:opEmu m:val="1"/>
<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>
end example]

Description |
|---|---|
val (value) |
Specifies a binary value for the property defined by the parent XML element. A value of 1 or true 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 0 or false 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 (§22.9.2.7). |
