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.

This attribute is included for backward compatibility with GML 2 and is deprecated with GML 3.
This identifer is superceded by "gml:id" inherited from AbstractGMLType. The attribute "gid" should not be used
anymore and may be deleted in future versions of GML without further notice.

In general this reference points to a CRS instance of gml:CoordinateReferenceSystemType
(see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the
location the URI points to. If no srsName attribute is given, the CRS must be specified as part of the larger context this
geometry element is part of, e.g. a geometric element like point, curve, etc. It is expected that this attribute will be specified
at the direct position level only in rare cases.

xs:positiveInteger

The "srsDimension" is the length of coordinate sequence (the number of entries in the list). This dimension is
specified by the coordinate reference system. When the srsName attribute is omitted, this attribute shall be omitted.

Ordered list of labels for all the axes of this CRS. The gml:axisAbbrev value should be used for these axis
labels, after spaces and forbiddden characters are removed. When the srsName attribute is included, this attribute is optional.
When the srsName attribute is omitted, this attribute shall also be omitted.

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.

A LineString is a special curve that consists of a single segment with linear interpolation. It is defined by two or more coordinate
tuples, with linear interpolation between them. It is backwards compatible with the LineString of GML 2, GM_LineString of ISO 19107 is
implemented by LineStringSegment.

            <xs:documentation>GML supports two different ways to specify the control points of a line string. 1. A sequence of "pos"
(DirectPositionType) or "pointProperty" (PointPropertyType) elements. "pos" elements are control points that are only part
of this curve, "pointProperty" elements contain a point that may be referenced from other geometry elements or reference
another point defined outside of this curve (reuse of existing points). 2. The "posList" element allows for a compact way to
specifiy the coordinates of the control points, if all control points are in the same coordinate reference systems and belong
to this curve only. The number of direct positions in the list must be at least two.</xs:documentation>
