/**
* A document that can be marked up with character and paragraph
* styles in a manner similar to the Rich Text Format. The element
* structure for this document represents style crossings for
* style runs. These style runs are mapped into a paragraph element
* structure (which may reside in some other structure). The
* style runs break at paragraph boundaries since logical styles are
* assigned to paragraph boundaries.
*
* Warning:
* Serialized objects of this class will not be compatible with
* future Swing releases. The current serialization support is
* appropriate for short term storage or RMI between applications running
* the same version of Swing. As of 1.4, support for long term storage
* of all JavaBeans™
* has been added to the java.beans package.
* Please see {@link java.beans.XMLEncoder}.
