RE: Tuelz Comment Tags

Somehow, I came to the understanding that the "comment tagz" can be whatever words we want to use, but with the correct "indicators." Am I wrong here or is there a prescribed set of "words" that the comment tagz have to be?

It would also seem to me that these are "utilities" that we use WHILE in SEO phase, yet, remove or change them, prior to uploading.

Are the comment tagz program specific or whatever the user deems them to say?

I'm not speaking of the "piece of HTML before and after." Rather, the tag itself. I understand that the tag "punctuation" must be specific.
