fo:leader is mainly used a) in table-of-contents to generate sequences of "." glyphs that separate titles from page numbers
b) to create entry fields in fill-in-the-blank forms c) to create horizontal rules for use as separators. You
define the look and use of fo:leader with the property "leader-pattern". It can have the following values: a) space. This
just creates an space. b) dots. This creates a sequence of "." c) rule. This creates a line. d) use-content. This creates a
repeating pattern of the content of fo:leader.

The dimensions of fo:leader are determined by the compound property leader-length. It consists of the
3 sub values: leader-length.minimum (default = 0), leader-length.optimum (default = 12pt), leader-length.maximum
(default = 100%). If you want to make sure, that leader-length has a fixed size, you should use the compound
property (p.e. leader-length="5cm"). If you want to fill the rest of the remaining space with dots in a table of
content, you can use the default values.

There are two properties which allow you to specify the looks of the dotted line. First
"leader-pattern-width". It specifies the length of one dot and the space up to the next dot.
Second leader-alignment. It can be used to make sure, the dots in different lines are parallel (only value "reference-area"
is supported).
