DeltaXML Control Attributes

Compare and Merge operations can be affected by the use of a number of control attributes in the DeltaXML namespace (see the Namespace Index for more details).

The table below lists the current set of control attributes with a brief description and links to relevant documentation for each of them.

N.B. Not all products allow the use of all of these attributes and may ignore or remove them when they are present in input documents.
