Reference_Syntax.beforeTarget = “auto | contentArea | pageArea | pageEven | pageFront | pageOdd”
The value of the beforeTarget property is expected to be compatible with the value of the before (deprecated) property. For instance, it would be considered an error for the before (deprecated) property to have a value of pageArea and the beforeTarget property to reference a content area, or vice versa.
