public interface ExpressionNode extends javax.xml.transform.SourceLocator
A class that implements this interface can construct expressions, give information about child and parent expressions, and give the originating source information. A class that implements this interface does not lay any claim to being directly executable.Note: This interface should not be considered stable. Only exprSetParent and exprGetParent can be counted on to work reliably. Work in progress.
