Attributes:
- axisLabels: a list of labels of the axes of the grid [gml/3.2.1/grids.xsd] (optional;
NCNameList),
- srsDimension: specifies the number of dimensions represented by the CRS and the positions in the GML Point [1] (optional;
xs:positiveInteger),
- srsName: references the Coordinate Reference System (CRS) that applies to the coordinates of the GML Point [2]. (optional;
xs:anyURI),
- uomLabels: Ordered list of unit of measure (uom) labels for all the axes of this CRS. The value of the string in the gml:catalogSymbol should be used for this uom labels, after spaces and forbiddden characters are removed. When the axisLabels attribute is included, this attribute shall also be included. When the axisLabels attribute is omitted, this attribute shall also be omitted [gml/3.1.1/base/geometryBasic0d1d.xsd]. (optional;
NCNameList),
- id: 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 [gmlBase.xsd]. (optional;
xs:ID); compare: Dev:Identities

*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this Wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
