Hi all,

Currently is not possible to specify in App-Schema mappings the default geometry of a mapped feature type,
note that having a default geometry defined is mainly important for WMS.

Most of the times a geometry will be available in the root feature type and a default geometry will be correctly
and automatically selected.

But in certain situations a feature type may have multiple geometries, or the 
geometry may be nested,
for example:

   <wfs:member>

      <st:Station gml:id​ = "station.st.1"​>

        <st:name>​station1​</st:name>

        <st:location>

          <st:name>​Europe​</st:name>

   *<st:position>*

   *         <gml:Point srsDimension​="2"*

   *           srsName​="http://www.opengis.net/gml/srs/epsg.xml#4326"​ >*

   *           <gml:pos>​-1.0 1.0​</gml:pos>*

   *         </gml:Point>*

   *       </st:position>*

        </st:location>

      </st:Station>

   </wfs:member>

In this case the geometry is nested inside the location element. I propose to 
extend App-Schema
mappings to allows us to define explicitly the default geometry:

   <FeatureTypeMapping>

      <sourceDataStore>​stations​</sourceDataStore>

      <sourceType>​stations​</sourceType>

      <targetElement>​st:Station​</targetElement>

   *<defaultGeometry>st:location/st:position</defaultGeometry>*

      <attributeMappings>

        <AttributeMapping>

          <targetAttribute>​st:Station​</targetAttribute>

          <idExpression>

            <OCQL>​strConcat('station.', ID)​</OCQL>

          </idExpression>

        </AttributeMapping>

Any objection or comments ?

Cheers,

Nuno Oliveira
