Errata: {foo}
Clarification: <bar>
Do you have an example of double-curly?
As an example, take this from the Wayback Machine archive of the White Wolf website:

Abomination [FN:R]
Cardtype: Action
Cost: 1 pool
Capacity: 4
Unique. Requires a ready
<non-Sterile> vampire. +1 stealth action.
Burn an untapped werewolf ally (such as Renegade Garou, Werewolf Pack or Black Spiral Buddy) in your ready region to put this card in play. This card becomes a unique Independent
{Abomination} vampire of 4 capacity with superior Protean [PRO]. You may move up to 4 blood from the acting vampire to this vampire. This vampire has +1 strength, gets an additional strike each round and gets an optional maneuver each combat. This vampire may attack any ready minion as a

action.
<non-Sterile> is a clarification, because the rules on Sterile already made it clear - but the card text was updated to be explicit.
{Abomination} was errata, because it was originally clanless (Abominations hadn't been invented in Final Nights).
