When reviewing the scenarios, several important points must be kept in mind. These principles reveal the processing methodology of Transformer templates as they transform source documents into target documents.
By specification, well-formed XML documents contain one and only one outer element, referred to as the root element or tag (node). To ensure this condition, all target documents receive an initial root node, Target_Root. This parent node is marked as a non-looping element.
Transformer does support multi-root element documents, however, most XML tools cannot process them.
Group nodes are XML elements that contain other groups or elements nested within (as children). They can also contain data but are frequently used to indicate logically related elements and repeating (nested) elements.
