The XSLT 1.0 specification is clear that the output does not have to be a
well-formed XML document, only a well-formed external general parsed entity.
Which means, in effect, something that would be a well-formed document if
you put a start and end tag around it. Whether you or I happen to like this
spec is somewhat irrelevant.
