22.1.2.20 chr (Character)
This element specifies the character to be attached to the base of an accent object, a group character object, or an n-ary operator object. When the parent element is accPr, the chr value should be within the range of (U+0300-U+036F) or (U+20D0-U+20EF). When the parent element is groupChrPr, the chr value should be a horizontal stretch character, such as U+2190 (LEFTWARD ARROW). When the parent element is naryPr, the chr value should be an n-ary operator such as U+222B (INTEGRAL).
When the element is present and the val attribute is absent, the default of the val attribute is empty which means the corresponding objects character is absent.
If this property is omitted for accPr, the default accent character is U+0302 (ACCENT, COMBINING CIRCUMFLEX). If this property is omitted for groupChrPr, the default character is U+23DF (BOTTOM CURLY BRACKET). If this property is omitted for naryPr, the default character is U+222B (INTEGRAL).
In other words, when the element is absent, the defaults are as follows:
accent object - Unicode character U+0302 (ACCENT, COMBINING CIRCUMFLEX)
group-character object - Unicode character U+23DF (BOTTOM CURLY BRACKET)
n-ary operator object - Unicode character U+222B (INTEGRAL)
[Example: Examples of accent characters are the dot, hat, and arrow in the following cases: .
For example, the following XML represents the acc .
<m:acc>
<m:accPr>
<m:chr m:val="̃"/>
</m:accPr>
<m:e>
<m:r>
<m:t>a</m:t>
</m:r>
</m:e>
</m:acc>
end example]
