A question about the SUNWcar pkg

A customer is asking about the SUNWcar package in relation to Solaris 11.

After I explained that I find that SUNWcar is a Solaris 10 package, the customer asked about this information:

root@sczescozdbadm04:~#  pkg list -af SUNWcar
NAME (PUBLISHER)                                  VERSION                    IFO
SUNWcar                                           0.5.11-0.133               --r
root@sczescozdbadm04:~#
The “r” in the O column indicates that this package has been renamed

I would like to have it confirmed that there is no Solaris 11 package named SUNWcar, I already explained a Solaris 10 package cannot be installed in to Solaris 11, but the customer is asking how it is "implemented" in Solaris 11 since the above output suggests it has been renamed.
