22.1.2.58 lit (Literal)
This element specifies that the characters in the run are literal; that is, they are to be interpreted literally and not be built up based on any implied mathematical meaning. This is especially useful for operators or other special characters that signal a need for build up to an OMML reader. These characters are often encountered during a given instance of mathematical text when presented in a 1-dimensional linear format, such as the linear format defined by Unicode Technical Note #28 (Sargent 2006).
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 XML, the + operator is treated literally and does not receive proper binary spacing:
<m:r>a</m:r>
<m:r>
<m:rPr>
<m:lit/>
</m:rPr>
<m:t>+</m:t>
</m:r>
<m:r>
<m:t>b</m:t>
</m:r>
As another example, consider the following Office Open XML Math markup:
<m:r>
<m:t>a</m:t>
</m:r>
<m:r>
<m:rPr>
<m:lit/>
</m:rPr>
<m:t>/</m:t>
</m:r>
<m:r>
<m:t>b</m:t>
</m:r>
This would be displayed as: . If built up, it would normally be converted to ; however, the presence of this element specifies that the solidus should be treated literally, resulting in .

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). |
