HTMLDOMImplementation | NN n/a IE n/a DOM 2
The W3C HTMLDOMImplementation object is an HTML-specific extension to the DOMImplementation object. Although not yet implemented in browsers, it may in the future provide an avenue to creating virtual HTML documents, much like the way you can create virtual XML documents in Netscape 6 and later. The one method that this object brings to the DOM is createHTMLDocument( ).
