 * Defines an iCalendar VVENUE component.
 *
 *  * 4.  Venue Component
 *
 *    Component Name: "VVENUE"
 *
 *    Purpose: Provide a grouping of component properties that describe an
 *    event venue.
 *
 *    Format Definition: A "VVENUE" calendar component is defined by the
 *    following notation:
 *      venuec  = "BEGIN" ":" "VVENUE" CRLF
 *              venueprop
 *              "END" ":" "VVENUE" CRLF
 *
 *      venueprop  = *(
 *
 *                ; the following are all REQUIRED,
 *                ; but MUST NOT occur more than once
 *
 *                uid
 *
 *                ; the following are optional,
 *                ; but MUST NOT occur more than once
 *
 *                name / description / street-address / extended-address /
 *                locality / region / country / postal-code / tzid / geo /
 *                location-type / categories
 *
 *                ; the following are optional,
 *                ; and MAY occur more than once
 *
 *                tel / url
 *              )
 *
 *    Description: A "VVENUE" calendar component is a grouping of component
 *    properties that represent a venue where an event occurs.  This
 *    extends the "LOCATION" property of "VEVENT" and "TODO" components,
 *    providing the ability to specify detailed information about the event
 *    venue.
