+/**
+ * $Id$
+ * 
+ * Created: [Apr 6, 2004]
+ *
+ * Defines a TZID iCalendar component property.
+ * 
+ * <pre>
+ *     4.8.3.1 Time Zone Identifier
+ *     
+ *        Property Name: TZID
+ *     
+ *        Purpose: This property specifies the text value that uniquely
+ *        identifies the &quot;VTIMEZONE&quot; calendar component.
+ *     
+ *        Value Type: TEXT
+ *     
+ *        Property Parameters: Non-standard property parameters can be
+ *        specified on this property.
+ *     
+ *        Conformance: This property MUST be specified in a &quot;VTIMEZONE&quot;
+ *        calendar component.
+ *     
+ *        Description: This is the label by which a time zone calendar
+ *        component is referenced by any iCalendar properties whose data type
+ *        is either DATE-TIME or TIME and not intended to specify a UTC or a
+ *        &quot;floating&quot; time. The presence of the SOLIDUS character (US-ASCII
+ *        decimal 47) as a prefix, indicates that this TZID represents an
+ *        unique ID in a globally defined time zone registry (when such
+ *        registry is defined).
+ *     
+ *             Note: This document does not define a naming convention for time
+ *             zone identifiers. Implementers may want to use the naming
+ *             conventions defined in existing time zone specifications such as
+ *             the public-domain Olson database [TZ]. The specification of
+ *             globally unique time zone identifiers is not addressed by this
+ *             document and is left for future study.
+ *     
+ *        Format Definition: This property is defined by the following
+ *        notation:
+ *     
+ *          tzid       = &quot;TZID&quot; tzidpropparam &quot;:&quot; [tzidprefix] text CRLF
+ *     
+ *          tzidpropparam      = *(&quot;;&quot; xparam)
+ *     
+ *          ;tzidprefix        = &quot;/&quot;
+ *          ; Defined previously. Just listed here for reader convenience.
+ *     
+ *        Example: The following are examples of non-globally unique time zone
+ *        identifiers:
+ *     
+ *          TZID:US-Eastern
+ *     
+ *          TZID:California-Los_Angeles
+ *     
+ *        The following is an example of a fictitious globally unique time zone
+ *        identifier:
+ *     
+ *          TZID:/US-New_York-New_York
+ * </pre>
