As of XFA version 2.8, this property is now deprecated. See breakAfter.target.Reference_Syntax.afterTarget = “auto | contentArea | pageArea | pageEven | pageFront | pageOdd”
The value of this property is expected to be compatible with the value of the after (deprecated) property. For instance, it would be considered an error for the after (deprecated) property to reference a page area and the afterTarget property to reference a content area, or vice versa.
