Needs to be added to DataStore (rather than a wrapper based) to allow for DataStores <br>Jody - You can see it as part of Query now. <br>OGC - apparenty they agree as well - it is part of WFS 1.1. </li> <li>GeoAPI - has reduced this to api to the FeatureStore construct Jody - since we are no longer using the FeatureReader/ReaderWriter in client code this would not be a bad idea. </li>
