Unified Archives are not a file backup mechanism so are not designed to provide that functionality. They are designed only for system cloning or bare metal recovery.
The internal structure of the unified archive file is metadata and a collection of ZFS send streams so it is not suitable for single file extraction.
The only option you have is to install a zone using the full archive and then manually extract the files you need.

Thank you for your answer, Darren. Is there any other tool in Solaris 11 to generate images where you can extract a single file, (but It must to be an image that you could convert to iso file) ??
There is no other tool for generating recovery images. Unified Archives are the only recovery mechanism we provide.
If you still have the older boot environments around on the system you should be able to mount them using beadm and copy the files from there.
