  =================================================================== --><complexType name="AbstractFeatureType" abstract="true"><annotation><documentation>
        An abstract feature provides a set of common properties. A concrete 
        feature type must derive from this type and specify additional 
        properties in an application schema. A feature may optionally 
        possess an identifying attribute ('fid').

        A simple geometry property encapsulates a geometry element.
        Alternatively, it can function as a pointer (simple-type link) 
        that refers to a remote geometry element.
      </documentation></annotation><sequence minOccurs="0"><element ref="gml:_Geometry"/></sequence><attributeGroup ref="gml:AssociationAttributeGroup"/></complexType><complexType name="FeatureAssociationType"><annotation><documentation>
        An instance of this type (e.g. a featureMember) can either 
        enclose or point to a feature (or feature collection); this 
        type can be restricted in an application schema to allow only 
        specified features as valid participants in the association. 
        When serving as a simple link that references a remote feature 
        instance, the value of the gml:remoteSchema attribute can be 
        used to locate a schema fragment that constrains the target 
        instance.
