Resolution of DOM XPath LC issue caro5

DOM XPath module last call issue caro1 was about clarifying in
the specification whether a null could be returned.  The 
resolution of this issue is to do nothing, because unless the
specification permits a null explicitly, then a null is not
permitted.  The working group has repeatedly rejected adding
to every described method that it cannot return a null.  There
is clear precedent throughout the DOM API.  None of the constructors
anywhere state that a null may not be returned, but they may
not because the description did not specify it.

Please let us know if you are, or are not, satisfied with this resolution.
