+In the bulk MapNode data, param1, instead of the typical light values, instead represents the
probability of that node appearing in the structure.
When passed to minetest.create_schematic, probability is an integer value ranging from 0 to 255:
- A probability value of 0 means that node will never appear (0% chance).
Schematic attributes

Currently supported flags: place_center_x, place_center_y, place_center_z

Placement of this decoration is centered along the X axis.

+Flag Specifier Format
+-----------------------
+Flags using the standardized flag specifier format can be specified in either of two ways, by string or table.
+The string format is a comma-delimited set of flag names; whitespace and unrecognized flag fields are ignored.
+Specifying a flag in the string sets the flag, and specifying a flag prefixed by the string "no" explicitly
+clears the flag from whatever the default may be.
+In addition to the standard string flag format, the schematic flags field can also be a table of flag names
+to boolean values representing whether or not the flag is set. Additionally, if a field with the flag name
+prefixed with "no" is present, mapped to a boolean of any value, the specified flag is unset.
+
+e.g. A flag field of value
+ {place_center_x = true, place_center_y=false, place_center_z=true}
+is equivalent to
+ {place_center_x = true, noplace_center_y=true, place_center_z=true}
+which is equivalent to
+ "place_center_x, noplace_center_y, place_center_z"
+or even
+ "place_center_x, place_center_z"
+since, by default, no schematic attributes are set.

+of interest to be recorded on generate, use minetest.set_gen_notify().
+Possible fields of the table returned are: dungeon, temple, cave_begin, cave_end, large_cave_begin, large_cave_end
