[ISO/IEC 29500-1 редакция 1]
22.1.2.123 zeroDesc (Phantom Zero Descent)
This element specifies that the phantom has zero descent. The descent of the contents of the phantom is not taken into account during layout. When this property is omitted, the phantom does have descent (zero descent is not applied).
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: In the following two examples, only the second has zero descent around the "y". Note that the radical is smaller than in the first case.
<m:phantPr>
<m:zeroDesc m:val="1"/>
</m:phantPr>
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). |
[Note: The W3C XML Schema definition of this element's content model (CT_OnOff) is located in §A.6.1. end note]
