(disabled vs. disabled="disabled") - use_trailing_solidus (boolean): should void elements have a trailing solidus? - space_before_trailing_solidus (boolean): if use_trailing_solidus is True, should a space be inserted before the trailing solidus? - escape_lt_in_attrs (boolean): should < be escaped as < in attribute values or left as-is? - escape_rcdata (boolean): should RCDATA content be escaped (< becomes <, > becomes > and & becomes &, >/> isn't strictly necessary but html5lib actually inherits this behavior from xml.sax.saxutils.escape()) - inject_meta_charset (boolean): in html5lib, ensures (if True) the serialized document has a <meta charset>; in a validator, would enforce (or not) the presence of the <meta charset> - omit_optional_tags (boolean): in html5lib, omit (if True) optional tags (such as </p>, </td>, </li>, etc.); in a validator, would allow (or not) omitted optional tags Actually, a particular combination of these flags are enough to make a polyglot document: http://code.google.com/p/html5lib/source/browse/python/src/html5lib/serializer/xhtmlserializer.py -- Thomas Broyer /tɔ.ma.bʁwa.je/
