<complexType name="BagType">
    <annotation>
        <documentation>
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.
