+# The two GeoPoints denote diagonally opposite corners of the box.
+#
+# If min_pt.latitude is NaN, the bounding box is "global", matching
+# any valid latitude, longitude and altitude.
+#
+# If min_pt.altitude is NaN, the bounding box is two-dimensional and
+# matches any altitude within the specified latitude and longitude
+# range.
