Due to the current technical limitations see the definition of <IS:lineString> and its attributes directly in the corresponding UML diagram (link to the railML® website).

Attributes:
- 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),
- 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.
