But I notice that your result was that shots and stations were
siblings, i.e. at the same level. It seems to me that is not only what
I was thinking and what I've seen, but also very practical.
I can picture either a file
full of points (to send to me friend with the cool graphics viewer),
or a file full of Shots (to send to another friend who wants to
start over and load the shots into some other software.

As to points and shots. I figure that any place a point or shot
can appear there should be the ability to specify points by name
or ID. Name when in near original form, by ID when the shot info
is coming out of an archiving program that contains named points
and shots that connect them.

Of course the pedantic amongst us can put both in all cases, when
generating caveXML from a very smart tool.

So, I'd say points are fundamental, if not primary,
so they should be referencable in anything that is something close
to 'raw data' by either their ID or by their ugly name.

I certainly agree with the ideas stated, just that I figure that
a file full of shots (with explicit stations names, not referencing
other
station structures) would certainly
be a form that a lot of 'original' data could arrive in.
I'm still thinking of the person who uses nothing trickier than an
XML editor (something that guides them through tags) to create
some survey shots.
