/*

* Summary: interface for an HTML 4.0 non-verifying parser
|
||||
* Description: this module implements an HTML 4.0 non-verifying parser
|
||||
* with API compatible with the XML parser ones. It should
|
||||
* be able to parse "real world" HTML, even if severely
|
||||
* broken from a specification point of view.
|
||||
