22.1.2.124 zeroWid (Phantom Zero Width)
This element specifies that the phantom has zero width. The width of the contents of the phantom is not taken into account during layout. When this property is omitted, the phantom does have width (zero width 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 folowing example, the second radical contains a phantom of the fraction a/b. The phantom has zero width, such that only the height grows to accommodate the hidden fraction:
<m:phantPr> <m:show m:val="0"/> <m:zeroDesc m:val="1"/> </m:phantPr>
end example]

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]
