A calendar is a discrete temporal reference system that provides a basis for defining temporal position to a resolution of one day.
gml:TimeCalendar adds one property to those inherited from gml:TimeReferenceSystem. A gml:referenceFrame provides a link to a gml:TimeCalendarEra that it uses. A  gml:TimeCalendar may reference more than one calendar era. 
The referenceFrame element follows the standard GML property model, allowing the association to be instantiated either using an inline description using the gml:TimeCalendarEra element, or a link to a gml:TimeCalendarEra which is explicit elsewhere.
