The W3C Markup Validator considers resources such as

  Content-Type: image/svg+xml;charset=iso-8859-1

  <?xml version='1.0' encoding='utf-8'?>
  ...

ISO-8859-1 encoded. If it is incorrect that the W3C Markup Validator
needs to change you either want that all processors treat the resource
ISO-8859-1 encoded in which case there is not really a point in not
allowing an optional charset parameter, or you want two classes of non-
interoperable processors, where some consider it ISO-8859-1 and others
consider it UTF-8. Which one is it?
