DAV property name: urn:schemas:calendar:descriptionurl
The PidNameCalendarDescriptionUrl property ([MS-OXPROPS] section 2.379) gets or sets the URL of a resource that contains a description of an appointment or meeting. This property is further specified in [RFC2445] section 4.2.1 as the ALTREP DESCRIPTION property, which is a Uniform Resource Identifier (URI). URIs can contain only US-ASCII characters, as specified in [RFC20]. The server SHOULD assume that URIs in this property contain only US-ASCII characters, and therefore the server does not perform character-encoding conversion.
