PyXML package - deprecate it?

Hi all, looks like PyXML package is deprecated since python itself provides xml mechanisms. When you look deeper, python's xml provides: "dom", "parsers", "sax", "etree" and PyXML provides: 'dom', 'marshal', 'parsers', 'sax', 'schema', 'utils', 'xpath', 'xslt' So, PyXML duplicates dom, parsers and sax (and looks like python's is in better shape). Is any package using marshall, schema or any other not in python itself? Deprecate PyXML or just remove duplicated parts? RR
