See section "Flag Specifier Format".
Currently supported flags: `place_center_x`, `place_center_y`, `place_center_z`.
Currently supported flags: `place_center_x`, `place_center_y`,
`place_center_z`, `force_placement`.
* `place_center_x`: Placement of this decoration is centered along the X axis.
* `place_center_y`: Placement of this decoration is centered along the Y axis.
* `place_center_z`: Placement of this decoration is centered along the Z axis.
* `force_placement`: Schematic nodes other than "ignore" will replace existing nodes.
