Bower looks nice ans simple at a first glance. How would building the
final .min.js work? Can that be integrated with redo? (Figuring out how
to build took me longest ;-)

Yes, we would also like to change the generator for xpaths in that vein
to produce paths that are anchored to the nearest ancestor with an
xml:id instead of the root.

That seems like a clean and easy way.
Maybe the plugins could put a callback into a hash with the field name
as a key.
Or setupAnnotation could send the field name as an event.

Yes, I am in contact with Rainer about this. I would like to use the
same field and format. Maybe we need to specify coordinate units.

I am loosely following the openannotation mailing list. Discussions on
concrete use of Selectors have been few, so I think it would be great to
have real-world use cases.
