/**
* The Domain controls access to its registered namespaces and performs
* initialization and connection management on behalf of the namespaces.
*
* <p>
* From the client application's perspective, the domain represents the only
* directly accessible object. It is through this object that the client
* gains access to namespaces, using the static method
* <code>Domain.accessNamespace()</code>.
* <p/>
* <p>
* Since the domain acts as the root of a directory service, it is a static
* entity and there can be only one domain per JVM.
* </p>
* <h3>Initialization</h3>
* <p>
* When Slide is first initialized, the Domain configuration is loaded.
* The location of the domain configuration file is given through the
* <code>org.apache.slide.domain</code> property in the Slide properties, or
* can be specified as argument to the static <code>Domain.init()</code>
* method.
* </p>
* <p>
* The domain configuration is written by an administrator and describes how
* each namespace is to be initialized. It includes information like:
* <ul>
* <li>
* The low-level services the namespace uses (structure store, content
* store, etc.)
* </li>
* <li>
* The namespace base topology, which includes the location of the base
* actions and paths in the namespace.
* </li>
* </ul>
* </p>
* <h3>Access and Security</h3>
* <p>
* After initialization is complete, the client application can request
* access to the domain. It uses one of the two methods:
* <ul>
* <li>
* {@link #accessNamespace Domain.accessNamespace(SecurityToken
securityObject, String namespace)}
* <br>
* Used to access a specific namespace. This method returns a
* <code>NamespaceAccessToken</code>, which thereafter must be used by
* the client application to perform operations on the namespace.
* <br><br>
* </li>
* <li>
* {@link #accessDomain Domain.accessDomain(SecurityToken
securityObject)}
* <br>
* Enumerates the registered namespaces with this domain. This allows
* application to browse the list of available namespaces.
* </li>
* </ul>
* </p>
* <p>
* The Domain uses an object (argument <code>securityObject</code>) to
* decide whether or not the client should be granted access. A good
* candidate is a reference to the client servlet or servlet context.<br><br>
* <i><small>Note: Currently, access control on namespaces is not
* implemented.</small></i>
* </p>
