Where do you see "document/encoded"?

I can see one redundant "encoding='utf-8'" (it specifies the default)
and several unused namespace declarations for "encoding" (in some
variety). All of which is harmless (though not strictly necessary).

Does it?

I see only the use of freedom granted by the various specifications.

For example:

  XML-Names requires that each used namespace prefix has an associated
  definition. But it does not forbid to define unused namespaces.

  XML uses "encoding='utf-8'" as the default but does not forbid
  to specify it explicitely.
