All attributes that may contain URIs.
- The attributes 'code' and 'codebase' are omitted, because they only exist for the <applet> tag. The time of Java applets has passed.
- The attribute 'icon' is omitted, because no browser implements the <command> tag anymore. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/command.
- The 'manifest' attribute is omitted because it only exists for the <html> tag. That tag only makes sense in a HTML-served-as-HTML context, in which case relative URLs are guaranteed to work.
