| 17 The MathML REC describes: | |
| 18 | |
| 19 The <msqrt> element is used to display square roots. | |
| 20 The syntax for <msqrt> is: | |
| 21 <msqrt> base </msqrt> | |
| 22 | |
| 23 Attributes of <msqrt> and <mroot>: | |
| 24 | |
| 25 None (except the attributes allowed for all MathML elements, listed in Section | |
| 26 2.3.4). | |
| 27 | |
| 28 The <mroot> element increments scriptlevel by 2, and sets displaystyle to | |
| 29 "false", within index, but leaves both attributes unchanged within base. The | |
| 30 <msqrt> element leaves both attributes unchanged within all its arguments. | |
| 31 These attributes are inherited by every element from its rendering environment, | |
| 32 but can be set explicitly only on <mstyle>. (See Section 3.3.4.) | |
