Portions of an Extensible Markup Language document, such as individual paragraphs or groups of paragraphs or fragments of text, are provided self-describing properties such as styles, fonts, list types, and the like. If such a portion of a document is subsequently copied or moved to a second document or to a different location in the first document, the self-describing properties provided for the portion travel with the portion to the second document or to the different location in the first document.
