Synopsis: 
    Validates stuff before a Put operation.

      - Checks to see that the user is not changing the instance's
        primary key.

      - Verifies the parent metabase node exists.

      - Checks the container class list of the parent node in the metabase
        to see if it contains the node we are trying to insert.

      - Throws on failure.  You should not continue with the put operation.
