Context Properties Set by a Component

The notification and authorization component can add new properties to the server, user, or presentation contexts, and set or retrieve the existing properties at any time during the life of the context. For example, the fee charged for viewing the title can be added to the presentation context when the title is opened. Then the billing cost can easily be retrieved from the context when the server sends notification that the title has been closed. Do not change any values set by the server. The server ignores such changes.
