The purpose of this model is to support both browsing and editing. As a result, the structure described by an HTML document is not exactly replicated by default. The element structure that is modeled by default, is built by the class <code>HTMLDocument.HTMLReader</code>, which implements the <code>HTMLEditorKit.ParserCallback</code> protocol that the parser expects. To change the structure one can subclass HTMLReader, and reimplement the method <code>getReader</code> to return the new reader implementation. The documentation for HTMLReader should be consulted for the details of the default structure created. The intent is that the document be non-lossy (although reproducing the HTML format may result in a different format). <p> The document models only HTML, and makes no attempt to store view attributes in it. The elements are identified by the <code>StyleContext.NameAttribute</code> attribute, which should always have a value of type <code>HTML.Tag</code> that identifies the kind of element. Some of the elements (such as comments) are synthesized. The HTMLFactory uses this attribute to determine what kind of view to build. <p> This document supports incremental loading. The <code>TokenThreshold</code> property controls how much of the parse is buffered before trying to update the element structure of the document. This property is set by the EditorKit so that subclasses can disable it. <p> The <code>Base</code> property determines the URL against which relative URLs are resolved. By default, this will be the <code>Document.StreamDescriptionProperty</code> if the value of the property is a URL. If a <BASE> tag is encountered, the base will become the URL specified by that tag. Because the base URL is a property, it can of course be set directly. <p> The default content storage mechanism for this document is a gap buffer (GapContent). Alternatives can be supplied by using the constructor that takes a Content implementation.<P><DL><DT><B>See Also: </B><DD><A
