BAse type for linear or vector linear relative spatial referencesystems. DEPRECATED. Use diggs:LinearSRS for linear referencing, EngineeringCRS for 2D relative referencing.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
