arc:first keyword to execute a section of a script for only the first iteration of an arc:call or arc:enum keyword. It is a convenient way to generate headings or to inspect the first item of a feed before going through the rest of the feed.
During the first iteration, the arc:first body executes before any other code within the arc:call or arc:enum, regardless of where the arc:first is located in the arc:call or arc:enum body. Therefore, CData recommends that you place arc:first at the top of the arc:call or arc:enum body.
If the scope has no items, neither arc:first nor arc:last is executed.
