I believe this is correct behavior. The designator indicates what attribute you want. It must match name, type, category and issuer (if any) with an Attribute in the Request.
The Attribute in the Request is labeled with its category. If you have a Secret subject attribute and a Secret resource attributed, the designator will find the right one. Keep in mind that the creation of policy and the provision of attribute values would normally take place at very different times and places.
