* MODULE NOTES:
* @update gess 4/1/98
*
* This pure virtual interface is used as the "glue" that connects the parsing
* process to the content model construction process.
*
* The icontentsink interface is a very lightweight wrapper that represents the
* content-sink model building process. There is another one that you may care
* about more, which is the IHTMLContentSink interface. (See that file for details).
