_types = { 'table' : 'list', 'tr' : 'list', 'td' : 'list' }

Valid types are

• zero -- return "" and skip processing subtree
• list -- list of the subelement values
• map -- map subelement-tags to their values
• mmap -- map subelement-tags to the list of their values
• mmapwn -- multimap when necessary (more than one ocor.)
