Schema documentation for component gml:BagType

A non-abstract generic collection type that can be used as a document element for a collection of any GML types - Geometries, Topologies, Features ... FeatureCollections may only contain Features. GeometryCollections may only contain Geometrys. Bags are less constrained they must contain objects that are substitutable for gml:_Object. This may mix several levels, including Features, Definitions, Dictionaries, Geometries etc. The content model would ideally be member 0..* members 0..1 member 0..* for maximum flexibility in building a collection from both homogeneous and distinct components: included "member" elements each contain a single Object an included "members" element contains a set of Objects However, this is non-deterministic, thus prohibited by XSD.

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.
