+ The &RepositoryProvider; only has a few methods that must be implemented. When the &DnaJcrDeployer; starts
+ up, it will dynamically load the &RepositoryProvider; implementation (as noted above) and call the <code>

+ The JBoss DNA JCR repository does support multiple repositories on the same server. Other JCR implementations
+ that don't support multiple repositories are free to return a singleton set containing any string from this method.
+ </para>
+ <para>
+ The other required method returns an open JCR &Session; for the user from the current request in a given repository
+ and workspace. The provider can use the &HttpServletRequest; to get the authentication credentials for the
+ HTTP user.

+ The <code>getSession(...)</code> method is used by most of the REST server methods to access the JCR
+ repository and return results as needed.

+ Finally, the <code>shutdown()</code> method signals that the web context is being undeployed and the JCR
+ repository should shutdown and clean up any resources that are in use.
