## Definition and Usage
The object is the root (top-level) node of an XSL-FO document.
The children of the object are a single object (which holds all page masters used in the document), an optional object, and one or more objects.
**Note:** An XSL-FO document can contain multiple objects (for example: each chapter in a document can be a separate object - it allows chapter-specific content such as: the chapter title, which can be placed in the header or footer).
