CanPlaceOn and CanDestroy Not Functioning

The CanPlaceOn and CanDestroy NBT tags for /replaceitem are comming up invalid. Either it's not fully implemented, not working, or us players aren't putting it into the command correctly. I fully understand the remainder of /replaceitem, and this is the only part I don't understand. Even if this is a duplicate, I would like to know how to properly enter the tag. Include an example, if possible.
