No improvements here. On v2 I gave you link pointing to specific
paragraph of our documentation which you need to apply - wrong wrapping.
Is there something unclear here?

Please
do

Unknown field... custom properties need vendor (axis,), type (boolean)
and description.

Same problem as in patch #1.

No, this must be false.
