  * 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 "VEVENT",

  *        "VTODO", "VJOURNAL" or "VFREEBUSY" 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        = "URL" urlparam ":" uri CRLF

  *     

  *          urlparam   = *(";" xparam)

  *     

  *        Example: The following is an example of this property:

  *     

  *          URL:http://abc.com/pub/calendars/jsmith/mytime.ics

  * </pre>
