[osis-core] When an osisID is not an osisID?

An osisID transformation file as I proposed could have a section like this:

<p osisID="John1.1-3">
<milestone osisRef="KJV.John.1.1" />
In the beginning was the word...
<milestone osisRef="KJV.John.1.2" />
He was with God in the beginning...
<milestone osisRef="KJV.John.1.3" />
Through him all things...
</p>

---------------------

Smart software would be able to refer to this file and figure
out that John1.1-3 contains KJV.John.1.1, KJV.John.1.2, and
KJV.John.1.3.

I'm not sure if those osisRefs should be containers, like
<reference> elements, or just milestones.
