Re: Point vs Range/Area Selectors?

Hi Rob,
I believe the 'Point' selector - or 'Cursor' as I was calling it in
Annotation Ontology - is an important feature to support.

In terms of implementation though, as you anticipated, you can go with the
offset (range="") or with the "quote" (match="") methodology in the case of
text.
So maybe we can formally define it as a particular case of those? Otherwise
we will have parallel definitions.

Best,
Paolo
