== Proposal ==

The WFS data downloader component is a simple widget which helps user downloading data from a WFS service. A form is displayed in order to select:
 * a service (usually referenced in a metadata record)
 * a layer (aka. feature type) (which may be referenced in a metadata record)
 * an output format
 * a projection
 * an area of interest (a bounding box)

The service and layer can be use to initialize the component.

If the service is not available, a warning is displayed.
If the layer is not published in the service, a warning is displayed.

A "download data" button is added to the view mode of the metadata when a WFS is registered in the current record.

TODO: 
 * Error reporting:
  * it could be nice to have some error reporting area - custom message displayed in the form which disappear after some secondes instead of modal popup)
 * Form
  * hide projection if only one define (we can't get server side supported projection ?)
  * hide service version with parameter (to make form simple) - an advanced/simple download form ?
  * format : use radio instead of combo ?
  * Download area: 
   * download area is the coordinates input or a map (if attached to the widget) extent. A rectangle could be better.
   * if coordinates are update, the map is not
 * IE support
