Some lines of the source document contain a parenthesized footnote reference, such as
"(1)"
. The
RepeatingGroup
contains a
Group
, whose purpose is to parse the footnote and insert its content in the output.
The
Group
contains a
Content
anchor that retrieves the footnote reference and stores it in a variable. The
Group
then activates a
RunParser
action that activates a secondary Parser. The secondary Parser finds the footnote referenced by the variable, parses it, and inserts the result in the output.
