"The simple PlainDocument class that you saw in the previous " +
"chapter is only capable of holding text. The more complex text " +
"components use a more sophisticated model that implements the " +
"StyledDocument interface. StyledDocument is a sub-interface of " +
"Document that contains methods for manipulating attributes that " +
"control the way in which the text in the document is displayed. " +
"The Swing text package contains a concrete implementation of " +
"StyledDocument called DefaultStyledDocument that is used as the " +
"default model for JTextPane and is also the base class from which " +
"more specific models, such as the HTMLDocument class that handles " +
"input in HTML format, can be created. In order to make use of " +
"DefaultStyledDocument and JTextPane, you need to understand how " +
"Swing represents and uses attributes.\n";
