Condition in accordance with OpenMAX

I’m sorry. I am Japanese.
It might be strange English because it uses the software of the
automatic translation.

If all “IL” “DL” “AL” specifications are not filled to conform to OpenMAX, is it useless?Or, does it only have to be satisfied either as much as one?

Thanks.

The implementer may choose to implement only one OpenMAX layer or any combination of the three layers.
