22.1.2.96 show

This element specifies the show property of the phantom phant. When 0 or false, the phant base e is hidden. If this element is omitted, the base e is shown. Whether the element is absent or present without the val attribute, the default of the val attribute is 1 meaning that this property is applied.

[Example: In the following example, there is a phantom of the fraction a/b in the second radical such that only the height is preserved. The fraction does not show.

<m:phantPr>
  <m:show m:val="0"/>
  <m:zeroDesc m:val="1"/>
</m:phantPr>

end example]

Attributes

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]
