When you drop a pin onto a LongReach location map, the title and subtitle properties are empty.
By default, LongReach will substitute the string 'Location' and 'Lat,Long values' for these empty values.
The location file is a simple JSON object, UTF-8 encoded.
You or a server program could modify/generate location files and change these values.
{"annotations":[{"title":"North Sydney Council","lng":"151.207471","lat":"-33.834345","subtitle":"200 Miller St"}]}
Now when you tap the pin, 'North Sydney Council' and '200 Miller St' will appear in the label.
