The group tag is used only within the body of a multiple tag to provide additional formatting control between subsets of a multirow data source. The tag takes a column name from the enclosing multiple tag as its only attribute. It repeats a template section as long as the value of -the column does not change from row to row.

Be careful when nesting several group tags. The group tag works very narrowly - it only looks at the column you provide it with and -so long as that column doesn't change, it keeps looping. E.g. if -you have 3 levels and the value of the outermost column changes but -the value of the middle column doesn't, the inner group tag won't -notice and will continue to loop. A workaround would be to create a -derived column, which contains e.g. "$f1,$f2", and use that as the -column for the inner group tag.
