- Overview of Statements
ST programs are XML data consisting of literal elements and ST statements. ST statements can be distinguished from literal elements (XML elements, attributes, and text) by their namespace "http://www.sap.com/transformation-templates", for which the prefix tt is used by convention.
During serialization and deserialization, literal elements are copied unchanged into a target document or consumed from a source document and compared. ST statements are executed according to their semantics.
Data is addressed using tree structures whose root nodes (data roots) are bound to ABAP data objects. The root nodes can always be addressed directly using their names. In addition, a current node can be defined, which can be addressed using $ref.
