Does anyone have documentation of the AreaFeature capability of the Trimble system.   Specifically, I'm looking for documentation on:

• The required content of the AreaFeature shapefile.
• The definition of the columns in the areaFeatureDictionary.txt file.
• An indication of whether the AreaFeature shapefile within the field data folder is referenced to the dictionary by ID, Name, or both.
• Info about how to create the IDs in the areaFeatureDictionary file.
• An indication of whether there can be an areaFeatureDictionary that is field specific, or if we must publish the area features definitions that we write for a specific field into the global areaFeatureDictionary file that is at the AgGPS folder.

Thanks
