2.1.42 Part 4 Section 188.8.131.52, tab (Custom Tab Stop)
WordPad supports this element. For the leader attribute, WordPad maps the "middleDot" value to "dot", and "heavy" to "underscore". The standard stipulates that the tab stop is with respect to the current page margin. WordPad does not take page margins into account when setting tab position. The value specified in the pos attribute is treated as the absolute tab position. On load, WordPad handles the ST_TabJc value "bar" as "left".
