While using some crypto implementations I got to see that many times a comment is added to the ciphertext.

The first thing I am wondering if it's some standard out there for this comments, and if so some links or informations about it. Would've asked to Google but don't know what to search.
Then, I would like to use a comment like the one showed above to store my ciphered messages as plaintext.
Assuming I want to do that for a message ciphered using AES, which informations should I store?
- Should I store the AES mode used for encryption ?
- Should I store the AES implementation I used ?
- Should I store the initialization vector ?
- Should I try to be compliant to some standards while storing these informations ?
