Cisco Application :: ACE Supports 4096-bit SSL Certificates?

I have some questions about the size of the certifcates in ACE module (ACE20). Reading the following link: [URL]
 
I can verify this text: 4096 (high security, level 4) - For software release A2(2.4) and later in the ACE module and software release A3(2.6) and later in the ACE appliance, you can use 4096-bit SSL certificates in chaingroups and authgroups. You can also import public certificates and keys that are 4096 bits in length.
 
We intend to use a certificate (CA) with keys of 4096 bits and according to the text of wiki, it's possible.
 
But if I check the guide [URL]
 
Somebody that already use certificates with 4096 bits in ACE20 module?
