+/**
+ * $Id$
+ * 
+ * Created: [Apr 6, 2004]
+ *
+ * Defines a URL iCalendar component property.
+ * 
+ * <pre>
+ *     4.8.4.6 Uniform Resource Locator
+ *     
+ *        Property Name: URL
+ *     
+ *        Purpose: This property defines a Uniform Resource Locator (URL)
+ *        associated with the iCalendar object.
+ *     
+ *        Value Type: URI
+ *     
+ *        Property Parameters: Non-standard property parameters can be
+ *        specified on this property.
+ *     
+ *        Conformance: This property can be specified once in the &quot;VEVENT&quot;,
+ *        &quot;VTODO&quot;, &quot;VJOURNAL&quot; or &quot;VFREEBUSY&quot; calendar components.
+ *     
+ *        Description: This property may be used in a calendar component to
+ *        convey a location where a more dynamic rendition of the calendar
+ *        information associated with the calendar component can be found. This
+ *        memo does not attempt to standardize the form of the URI, nor the
+ *        format of the resource pointed to by the property value. If the URL
+ *        property and Content-Location MIME header are both specified, they
+ *        MUST point to the same resource.
+ *     
+ *        Format Definition: The property is defined by the following notation:
+ *     
+ *          url        = &quot;URL&quot; urlparam &quot;:&quot; uri CRLF
+ *     
+ *          urlparam   = *(&quot;;&quot; xparam)
+ *     
+ *        Example: The following is an example of this property:
+ *     
+ *          URL:http://abc.com/pub/calendars/jsmith/mytime.ics
+ * </pre>
+ *
