Defaults to ``True``. :arg quote_attr_values: Whether to quote attribute values that don't require quoting per legacy browser behavior (``"legacy"``), when required by the standard (``"spec"``), or always (``"always"``). Defaults to ``"legacy"``. :arg quote_char: Use given quote character for attribute quoting. Defaults to ``"`` which will use double quotes unless attribute value contains a double quote, in which case single quotes are used. :arg escape_lt_in_attrs: Whether or not to escape ``<`` in attribute values. Defaults to ``False``. :arg escape_rcdata: Whether to escape characters that need to be escaped within normal elements within rcdata elements such as style. Defaults to ``False``. :arg resolve_entities: Whether to resolve named character entities that appear in the source tree. The XML predefined entities < > & " ' are unaffected by this setting. Defaults to ``True``. :arg strip_whitespace: Whether to remove semantically meaningless whitespace. (This compresses all whitespace to a single space except within ``pre``.) Defaults to ``False``. :arg minimize_boolean_attributes: Shortens boolean attributes to give just the attribute value, for example:: <input disabled="disabled"> becomes:: <input disabled> Defaults to ``True``. :arg use_trailing_solidus: Includes a close-tag slash at the end of the start tag of void elements (empty elements whose end tag is forbidden). E.g. ``<hr/>``. Defaults to ``False``. :arg space_before_trailing_solidus: Places a space immediately before the closing slash in a tag using a trailing solidus. E.g. ``<hr />``. Requires ``use_trailing_solidus=True``. Defaults to ``True``. :arg sanitize: Strip all unsafe or unknown constructs from output. See :py:class:`html5lib.filters.sanitizer.Filter`. Defaults to ``False``. :arg omit_optional_tags: Omit start/end tags that are optional. Defaults to ``True``. :arg alphabetical_attributes: Reorder attributes to be in alphabetical order.
