CA vs. CA IOS ?

If things of this nature should be posted to a different list, please let me know (the mail addr) and I will post there. What is the the difference between the CA and CC trees ?? According to release notes, They each support a different family of PA interfaces etc. Is this to say that one does not support what the other does ??
