IUccCategoryContext exposes properties and methods useful for discovering the collection of category instances within the given category context as well as the publisher of the instances. An important property of IUccCategoryContext is the Name property which identifies the category context itself.

The collection of category instances within a category context can be queried to return all instances in a given ACL container. With the addition of an additional query parameter, a client can query for a specific category instance within the collection of instances.

In an active subscription, the server sends presence updates at the category context level. It does not send the status for just one category instance at a time. To receive update notification for individual category instances, advise for events on a category instance when handling the OnCategoryInstanceAdded event.
