In transforming from one type of editable document form to another, the problem of preserving unsupported controls from the first data stream for subsequent retransformation needs to be addressed. It would obviously be efficient to preserve any unsupported controls for later use when the transformation process is reversed without violating the logical integrity of the transformed data stream. In addition, it would be advantageous to display the unsupported control so that the terminal user is aware that it is there and can act accordingly. It is assumed that the initial data stream is OIIA-L3 (Office Information Interchange Architecture, Level 3), hereinafter identified as L3, and that the desired transformation is from L3 to DCF (Document Composition Facility).
