What does it do?
An ST program must consist of valid XML data that is structured as shown here.
The first line < ? ... ?> serves to identify the transformation type (ST). It does not need to be entered because the syntax check adds it automatically.
The elements of the namespace http://www.sap.com/transformation-templates are ST statements. The namespace prefix tt is used in this documentation as a convention for this namespace. ST statements can be XML elements or attributes. All other components of an XML element are so called literal elements, which means that they have no semantics within the ST language.
Possible elements of an ST program are:
Type definitions using tt:type.
A root element tt:transform.
Various data declarations using tt:root, tt:parameter, and tt:variable.
A main template defined with tt:template and any number of subtemplates. A template is a pattern for the XML data into which ABAP data is serialized or from which data is deserialized. These elements can be in any order.



Latest notes:
In this documentation and in the example programs, double quotation marks (') are used as outer quotation marks and single quotation marks (') as inner quotation marks. However, as usual in XML, this is not mandatory. For example, 'not-initial(ref('X.Y'))' can be written instead of 'not-initial(ref('X.Y'))'.
