Annotations
gml:TimeCalendarEra inherits basic properties from gml:DefinitionType and has the following additional properties:
-	gml:referenceEvent is the name or description of a mythical or historic event which fixes the position of the base scale of the calendar era.  This is given as text or using a link to description held elsewhere.
-	gml:referenceDate specifies the date of the referenceEvent expressed as a date in the given calendar.  In most calendars, this date is the origin (i.e., the first day) of the scale, but this is not always true.
-	gml:julianReference specifies the Julian date that corresponds to the reference date.  The Julian day number is an integer value; the Julian date is a decimal value that allows greater resolution.  Transforming calendar dates to and from Julian dates provides a relatively simple basis for transforming dates from one calendar to another.
-	gml:epochOfUse is the period for which the calendar era was used as a basis for dating.

Attributes
QName Type Fixed Default Use Annotation
gml:id ID required
The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.
