/**
* This interface is OBSOLETE and in the process of being REMOVED.
* Do NOT implement!
*
* This file declares the concrete HTMLContentSink class.
* This class is used during the parsing process as the
* primary interface between the parser and the content
* model.
*
* After the tokenizer completes, the parser iterates over
* the known token list. As the parser identifies valid
* elements, it calls the contentsink interface to notify
* the content model that a new node or child node is being
* created and added to the content model.
*
* The HTMLContentSink interface assumes 4 underlying
* containers: HTML, HEAD, BODY and FRAMESET. Before
* accessing any these, the parser will call the appropriate
* OpennsIHTMLContentSink method: OpenHTML,OpenHead,OpenBody,OpenFrameSet;
* likewise, the ClosensIHTMLContentSink version will be called when the
* parser is done with a given section.
*
* IMPORTANT: The parser may Open each container more than
* once! This is due to the irregular nature of HTML files.
* For example, it is possible to encounter plain text at
* the start of an HTML document (that precedes the HTML tag).
* Such text is treated as if it were part of the body.
* In such cases, the parser will Open the body, pass the text-
* node in and then Close the body. The body will likely be
* re-Opened later when the actual <BODY> tag has been seen.
*
* Containers within the body are Opened and Closed
* using the OpenContainer(...) and CloseContainer(...) calls.
* It is assumed that the document or contentSink is
* maintaining its state to manage where new content should
* be added to the underlying document.
*
* NOTE: OpenHTML() and OpenBody() may get called multiple times
* in the same document. That's fine, and it doesn't mean
* that we have multiple bodies or HTML's.
*
* NOTE: I haven't figured out how sub-documents (non-frames)
* are going to be handled. Stay tuned.
