  First, you don't have to quote everything.  Just:

  The same applies here.  Attributes and their values don't need to be quoted.  Only string expansions.

  Then the attributes being looked at don't exist in the packet

  Yes.

  You can do that, but if Cisco-SSG-Service-Info doesn'tt exist, it will result in the above error.

  That still works.
