An instance of this interface is an context as defined by the extension point
org.eclipse.ui.contexts.
An instance of this interface can be obtained from an instance of
IContextManager for any identifier, whether or not an context
with that identifier is defined in the extension registry.
The handle-based nature of this API allows it to work well with runtime
plugin activation and deactivation. If a context is defined, that means that
its corresponding plug-in is active. If the plug-in is then deactivated, the
context will still exist but it will be undefined. An attempts to use an
undefined context will result in a NotDefinedException being
thrown.
This interface is not intended to be extended or implemented by clients.
