//:The PtCallCapabilities object represents the initial capabilities interface for the PtCall.
// This object supports basic queries for the core classes.
// <p>
// Applications obtain the static PtCall capabilities via the PtProvider.getCallCapabilities()
// method, and the dynamic capabilities via the PtCall.getCapabilities() method. This Class
// is used to represent both static and dynamic capabilities.
// <p>
// Any object which extends the PtCall class should also extend this class to provide additional
// capability queries for that particular package.
