You can create structured document as structured XML documents or as .fm documents.
Structured authoring is based on elements. An element in a document contains text, image, or other elements. A structured document is made up of a hierarchy of elements.
The elements in a structured document depend on the structured application on which the document is based. A structured application defines the structural and formatting rules that are then used by the structured documents that use the application. For details, see .
When you create a structured document in FrameMaker, you need to specify the structured application to use.
