Clearly (by observation), Mediawiki passes HTML 4 entities through as entities but anything else (including HTML5 entities) are &ersand; escaped.
To be a well-formed document, rules must be established about the declaration and treatment of entities. Tags are case sensitive, with attributes delimited with quotation marks. Empty elements have rules established. Overlapping tags invalidate a document. Ideally, a well-formed document conforms to the design goals of XML.
