<?tcusts5>
Description
Sets the value of x-height for Maths, which is used to define measurements in the following instances:
• For \sqrt (square root) in displaymode: the minimum clearance between the contents of the root and the bar above is the rule width + 1/4 of x-height.
• For accents: the minimum height of a placed accent.
• For superscripts: the subscripts should not be placed above 4/5 of x-height
• For subscripts: solitary subscripts should not be placed below 1/4 of x-height.
• For a joint sub- and superscript, the superscript should be at least 4/5 of x-height above the baseline.
The value of this property is a percentage of the text height value for the stream set via <?th>.
