|
The MathML REC describes:
|
|
|
|
The <msqrt> element is used to display square roots.
|
|
The syntax for <msqrt> is:
|
|
<msqrt> base </msqrt>
|
|
|
|
Attributes of <msqrt> and <mroot>:
|
|
|
|
None (except the attributes allowed for all MathML elements, listed in Section
|
|
2.3.4).
|
|
|
|
The <mroot> element increments scriptlevel by 2, and sets displaystyle to
|
|
"false", within index, but leaves both attributes unchanged within base. The
|
|
<msqrt> element leaves both attributes unchanged within all its arguments.
|
|
These attributes are inherited by every element from its rendering environment,
|
|
but can be set explicitly only on <mstyle>. (See Section 3.3.4.)
