Node.replaceChild with newChild being a DocumentFragment

DOM L2 WD (as well as L1 spec indeed) appears to fail to be clear as to
what behavior to be expected when Node.replaceChild is invoked with its
newChild being a DocumentFragment. Other methods such as insertBefore
and appendChild are explicitly stated as being aware of DocumentFragment
on the other hand.

I suggest that DOM L2 be specific on this point.
I know of DOM implementations which behaves differently upon the operation
described above: one raises HIERARCHY_REQUEST_ERR exception, the other
succeeds so that the net result is the same as if removeChild was
called following insertBefore. This is not apparently a desirable
situation for DOM interoperability thus needs to be explicitly described
in the spec one way or the other.
