h-rpg-rule
I think this is a fine globally available format for all RPGs. A rule is a simple thing: It has a name and a bunch of details. This isn't d20-specific, either. Any game that has a section heading with several sentences as rules, a bulleted list of details, or even a simple Name. Lorem ipsum dolor sit amet style can use this.
