Schema documentation for component diggs:AbstractDiggsType

The root abstract type for all DIGGS objects. This type extends GML's AbstractGMLType but restricts it to require a gml:id attribute. The gml:id serves as a unique identifier for the object within the DIGGS document and enables XML linking and referencing. All DIGGS types that need to be referenced ultimately derive from this base type, ensuring every object in the schema has a unique identifier for cross-referencing and data integrity.

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.
