yes.  the normal to-spec, but restricted to variables, and their parts.
i.e. not partnerlinks, etc.  in the spec, this is the "first" form of the
to-spec referred to in 9.3, and extended for executable processes in 14.3

unless i'm mistaken, <copy> can be used here.

you are correct.  this should be added.  i believe that this is the only one
of the new 4, though, that should have "select" be optional.
