+/**
+ * $Id$
+ * 
+ * Created: [Apr 6, 2004]
+ *
+ * Defines a CLASS iCalendar property.
+ * 
+ * <pre>
+ *     4.8.1.3 Classification
+ *     
+ *        Property Name: CLASS
+ *     
+ *        Purpose: This property defines the access classification for a
+ *        calendar component.
+ *     
+ *        Value Type: TEXT
+ *     
+ *        Property Parameters: Non-standard property parameters can be
+ *        specified on this property.
+ *     
+ *        Conformance: The property can be specified once in a &quot;VEVENT&quot;,
+ *        &quot;VTODO&quot; or &quot;VJOURNAL&quot; calendar components.
+ *     
+ *        Description: An access classification is only one component of the
+ *        general security system within a calendar application. It provides a
+ *        method of capturing the scope of the access the calendar owner
+ *        intends for information within an individual calendar entry. The
+ *        access classification of an individual iCalendar component is useful
+ *        when measured along with the other security components of a calendar
+ *        system (e.g., calendar user authentication, authorization, access
+ *        rights, access role, etc.). Hence, the semantics of the individual
+ *        access classifications cannot be completely defined by this memo
+ *        alone. Additionally, due to the &quot;blind&quot; nature of most exchange
+ *        processes using this memo, these access classifications cannot serve
+ *        as an enforcement statement for a system receiving an iCalendar
+ *        object. Rather, they provide a method for capturing the intention of
+ *        the calendar owner for the access to the calendar component.
+ *     
+ *        Format Definition: The property is defined by the following notation:
+ *     
+ *          class      = &quot;CLASS&quot; classparam &quot;:&quot; classvalue CRLF
+ *     
+ *          classparam = *(&quot;;&quot; xparam)
+ *     
+ *          classvalue = &quot;PUBLIC&quot; / &quot;PRIVATE&quot; / &quot;CONFIDENTIAL&quot; / iana-token
+ *                     / x-name
+ *          ;Default is PUBLIC
+ *     
+ *        Example: The following is an example of this property:
+ *     
+ *          CLASS:PUBLIC
+ * </pre>
