Hmmm... apparently not:

(Subsection 14.1, Syntax Rules of DECLARE CURSOR)

11) If an <updatability clause> of FOR UPDATE with or without a <column
name list> is specified, then INSENSITIVE shall not be specified and QE
shall be updateable.

I'm not really sure I see the point of this restriction, though...
