Element gml:AbstractDatum
Namespace http://www.opengis.net/gml/3.2
Annotations
 
A gml:AbstractDatum specifies the relationship of a coordinate system to the
earth, thus creating a coordinate reference system. A datum uses a parameter or set of
parameters that determine the location of the origin of the coordinate reference system.
Each datum subtype may be associated with only specific types of coordinate systems. This
abstract complex type shall not be used, extended, or restricted, in a GML Application
Schema, to define a concrete subtype with a meaning equivalent to a concrete subtype
specified in this document.

QName Type Use Annotation
gml:id ID required 
Database handle for the object. It is of XML type ID, so is constrained to be
unique in the XML document within which it occurs. An external identifier for the object in
the form of a URI may be constructed using standard XML and XPointer methods. This is done
by concatenating the URI for the document, a fragment separator, and the value of the id
attribute.
