* How do I release this?
  * I must be able to perform a 'rolling' release of this in a live system w/o
    causing a service interruption
  * does it break backward compatability with existing users of the api/system/etc
  * do we need to cut a new XSD?  A new version (URI prefix) of our API?
  * did we make updates to checkouts/SNAPSHOT deps? Do we need to cut new versions of project deps?
  * how do I support existing users?
  * in what order do the affected systems need to be released?
  * are there system or service configuration changes that are required?
* What are the Security implications of my change?
