This interface supports SDx revisioning, typically accessed by a Revise command on the publishing tool’s menu. Before SmartPlant Client version 3.7, tool-published documents were revised during the publish operation. A publishing tool now has the option to use SDx revisioning schemes. Integration with SDx currently requires that a tool support SDx revisioning and return True when SP Client passes SPFRevisions to the tool’s implementation of SupportsFeature.
The separation of revise from publish requires the tool to support a separate revisioning operation to revise documents and to save revisions values for each document.
