Annotations

The intended use of TopoPoint is to appear within a point feature to express the structural and possibly geometric relationships of this point to other features via shared node definitions. Note the orientation assigned to the directedNode has no meaning in this context. It is preserved for symmetry with the types and elements which follow.

Annotation

gml:id

optional

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.
