Only a few higher-numbered codes can be created using entity names, but all can be created by decimal number character reference.
Some tags that resemble HTML are actually MediaWiki parser and extension tags, and so are actually wiki markup. HTML included in pages can be validated for HTML5 compliance by using validation.
