/**
* <pre>
* <p>
* Contains interfaces for schema object registry services and simple POJO
* implementations of these services. Other helper interfaces and classes are
* included for handling monitoring of these services.
* </p>
* <p>
* These services and their POJO implementations are purposefully kept really
* simple here for a reason. When one looks at these interfaces they stop and
* think why even bother having them when you can just use a map of objects
* somewhere. These simple services can and will get more complex as other
* facilities come into play namely the object builders that populate these
* registries. There might also be caching going on as well as disk based
* store access. Finally dependencies become an issue and sometime bootstrap
* instances of these components are required by the system. So these simple
* watered down interfaces and their POJO's have been pruned from previously
* complex environment specific versions of them.
* </p>
* <p>
* Some key points to apply to services and their POJO impls in this package:
* <ul>
* <li>registries only register and allow for lookups: its that simple!</li>
* <li>don't worry if they change over time</li>
* <li>don't worry about how they get populated</li>
* <li>don't worry who or what does the populating</li>
* <li>don't worry about where the information comes from</li>
* </ul>
* </p>
