The heuristic may not take account of not-well-formed documents, for
instance not-wf/sa/001.xml in the W3C DOM test suite.

The XML spec says

  An XML processor MUST always pass all characters in a document that
  are not markup through to the application. A  validating XML processor
  MUST also inform the application which of these characters constitute
  white space appearing in element content.

It doesn't say you have to report ignorable white space before or after
the document root at all as these are not in element content.
