Title: Needed to scale back on named HTML entities

HTML5 can be written in either an HTML or XML serialisation. The XML serialisation (aka XHTML5) is not actually XHTML but valid XML which does not recognise any named entities except for <, >, &, " and '.

As a result, to maintain the common denominator approach, most named entities have been deleted.
