Author:

mocleiri a propertyName parameter that can be used to adjust which columns are returned by the request. The default OpenLayers implementation does not support this as it needs the spatial data for the selection of a specific feature. However for some cases you don't need the spatial definition but want to know values for certain non spatial columns. This control lets you specify which specific columns you want returned (in GML).
