As an example, we now have faa-regulations, but there are many parts to the FAA regulations, such as 14 CFR 61/91/121/135/etc.
The regulations that apply are to something can be very different depending on what part applies, so we have tags for them. Right now FAA tags are named like far-91 but what would be the best naming scheme for them? FAR is a (commonly used) nickname for "14 CFR", but is not the official term.
Since faa-regulations is so commonly used, I would like to see the tag name begin with "faa" so that we can see a list of the tags that are used together when we first start typing the regulatory authority tag name. This would be particularly for less commonly used/known regulations in that someone can simply enter the regulatory authority tag and see the major parts of their regulations as well. Some suggestions:
