- *  \brief MD_CACHE log-message IDs and their descriptions
+/* To add new message IDs, append new identifiers at the end of the list.
  *
- */
-
-/* NOTE: Rules for message additions
- * 1) Each instance of a message is _better_ left with a unique message ID, even
- *    if the message format is the same. Reasoning is that, if the message
- *    format needs to change in one instance, the other instances are not
- *    impacted or the new change does not change the ID of the instance being
- *    modified.
- * 2) Addition of a message,
- *       - Should increment the GLFS_NUM_MESSAGES
- *       - Append to the list of messages defined, towards the end
- *       - Retain macro naming as glfs_msg_X (for redability across developers)
- * NOTE: Rules for message format modifications
- * 3) Check acorss the code if the message ID macro in question is reused
- *    anywhere. If reused then then the modifications should ensure correctness
- *    everywhere, or needs a new message ID as (1) above was not adhered to. If
- *    not used anywhere, proceed with the required modification.
- * NOTE: Rules for message deletion
- * 4) Check (3) and if used anywhere else, then cannot be deleted. If not used
- *    anywhere, then can be deleted, but will leave a hole by design, as
- *    addition rules specify modification to the end of the list and not filling
- *    holes.
