> Ranger policy engine makes several evaluation context attributes available in expressions, like `REQ.accessType`, `RES._ownerUser` `RES.database`, `RES.table`. This should be extended to make attributes supplied by the application (like trx_amount, approval_status), so that policies can refer to these attributes in making decisions. For example:
>  
> {noformat}
>  CTX_ATTR.trx_amount > 10000 && CTX_ATTR.approval_status != 'approved'{noformat}
>
