* This pure virtual interface is used as the "glue" that connects the parsing

|
|
* 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).
