An instance of this interface is a category as defined by the extension
point org.eclipse.ui.activities .
An instance of this interface can be obtained from an instance of
IActivityManager for any identifier, whether or not a category
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, which can cause dynamic changes to the
extension registry.
This interface is not intended to be extended or implemented by clients.
