The implied grouping makes it unclear what the parentheses mean. For examples, attribute values on non-HTML elements in an HTML document seem not to be part of "Everything else", but are not mentioned in the rest of the section either. 111449 1 contributor 2014-09-12 17:48:48 +0000 Checked in as WHATWG revision r8764.
