web-server/data/release/demo/WFS_getFeatureIntersects-1.1.xml

<!-- Performs an intersects against a point.  This is functionally -->
<!-- equivalent to <Not><Disjoint>.  This call can be used by a    -->
<!-- client application to select a feature clicked on.  

     This will search through the dataset and return any polygons that
     contain the search point.  
     
     If you were searching in a point or line dataset, you might want
     to make a little polygon to search with instead of a single point
     so the user doesnt have to *exactly* click on the (mathematically
     infinitely thin) line or point.
