Solution modifiers and Update

Judging by the last draft which included a grammar:

   http://www.w3.org/TR/2009/WD-sparql11-update-20091022/

one cannot issue an Update request which includes LIMIT or ORDER BY.

That means one can CONSTRUCT things that one cannot INSERT:

   CONSTRUCT { ?s a <urn:Foo> } WHERE { ?s a ?y } ORDER BY ?s LIMIT 1

is valid, but

   INSERT { ?s a <urn:Foo> } WHERE { ?s a ?y } ORDER BY ?s LIMIT 1

is not.

Is there any reason for this, or is it simple oversight? Issue 27's  
resolution in favor of allowing subqueries in Update forms would seem  
to make this possible, so I don't see any reason to make it more  
complicated than necessary.

Thanks,

-R
