正如下标文本一样，可使用XSL - FOvertical - align属性来处理上标文本。
Just as with subscript text, you use the XSL-FO vertical-align property to handle superscript text. Here's an HTML sample.
很多书写用字母(比如：法语)需要上标或下标才能正确展示。在这些情况下，SUB和SUP元素应该用来标记文本。
Many scripts (e. g., French) require superscripts or subscripts for proper rendering. The sub and sup elements should be used to markup text in these cases.
