Re: Count of annotations by xpath?

Hi Ron,

Currently the protocol does not address bulk operations such as counting,
summarizing, filtering or searching.  It only addresses item level
operations of create, retrieve, update and delete.

A future version of the protocol might include such methods, and it would
be great to work on a list of desired operations, with use cases and
implementations to demonstrate the necessity of the work.
