| Entity Type | Table |
| Description | A sequence of one or more line segments, which need not be connected (i.e., a line can have gaps). The line segments are a connected sequence of two or more points. For simplicity, there is no explicit line segment entity; line segmentation is merely an attribute of the vertices. |
