Splitting across a content area or page is only relevant for text based field and draw objects; specifically, those using the textEdit object.
Reference_Syntax.intact = “none | contentArea”
none (default for subforms and field objects)
The determination of whether an object will be rendered intact within a content area or page is delegated to the processing application. It is possible that a subform could be split across a content area or page. This value is the default when the parent container’s layout is tb, lr-tb, or table. The field and draw objects will not split if the parent container does not allow splitting, itself.
