michael@0:  *     4.8.1.3 Classification
michael@0:  *     
michael@0:  *        Property Name: CLASS
michael@0:  *     
michael@0:  *        Purpose: This property defines the access classification for a
michael@0:  *        calendar component.
michael@0:  *     
michael@0:  *        Value Type: TEXT
michael@0:  *     
michael@0:  *        Property Parameters: Non-standard property parameters can be
michael@0:  *        specified on this property.
michael@0:  *     
michael@0:  *        Conformance: The property can be specified once in a "VEVENT",
michael@0:  *        "VTODO" or "VJOURNAL" calendar components.
michael@0:  *     
michael@0:  *        Description: An access classification is only one component of the
michael@0:  *        general security system within a calendar application. It provides a
michael@0:  *        method of capturing the scope of the access the calendar owner
michael@0:  *        intends for information within an individual calendar entry. The
michael@0:  *        access classification of an individual iCalendar component is useful
michael@0:  *        when measured along with the other security components of a calendar
michael@0:  *        system (e.g., calendar user authentication, authorization, access
michael@0:  *        rights, access role, etc.). Hence, the semantics of the individual
michael@0:  *        access classifications cannot be completely defined by this memo
michael@0:  *        alone. Additionally, due to the "blind" nature of most exchange
michael@0:  *        processes using this memo, these access classifications cannot serve
michael@0:  *        as an enforcement statement for a system receiving an iCalendar
michael@0:  *        object. Rather, they provide a method for capturing the intention of
michael@0:  *        the calendar owner for the access to the calendar component.
michael@0:  *     
michael@0:  *        Format Definition: The property is defined by the following notation:
michael@0:  *     
michael@0:  *          class      = "CLASS" classparam ":" classvalue CRLF
michael@0:  *     
michael@0:  *          classparam = *(";" xparam)
michael@0:  *     
michael@0:  *          classvalue = "PUBLIC" / "PRIVATE" / "CONFIDENTIAL" / iana-token
michael@0:  *                     / x-name
michael@0:  *          ;Default is PUBLIC
michael@0:  *     
michael@0:  *        Example: The following is an example of this property:
michael@0:  *     
michael@0:  *          CLASS:PUBLIC
