This specification modifies the definition of the "DESCRIPTION" property to allow it to be defined in an iCalendar object. The following additions are made to the definition of this property, originally specified in Section 220.127.116.11 of [RFC5545].
This property specifies the description of the calendar.
This property can be specified multiple times in an iCalendar object. However, each property MUST represent the description of the calendar in a different language.
This property is used to specify a lengthy textual description of the iCalendar object that can be used by calendar user agents when describing the nature of the calendar data to a user. Whilst a calendar only has a single description, multiple language variants can be specified by including this property multiple times with different "LANGUAGE" parameter values on each.
