Schema documentation for component diggs:AbstractDiggsType

Abstract root type of all DIGGS objects. Extends gml:AbstractGMLType and requires a gml:id attribute, which identifies the object within the DIGGS document and allows it to be referenced with xlink. All DIGGS types that can be referenced derive from it.

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.
