A formalist take on the intervention that launched a 1000 memes: why 'specific and limited'? A (quick and superficial) search through the usual suspects -- ICJ/ILC/RIAA/UN Ybks/conferences -- shows no context where that phrase has established technical meaning.

(1) Law of treaties angle. ‘Specific and limited’ relevant not for what it is but for what it is not; if one were trying to describe a breach that is NOT material, a phrase along these lines would probably come to mind. Purpose: preclude termination/suspension by the other Party.
(2) Law of responsibility angle. Under Withdrawal Agreement/law of countermeasures, seriousness/gravity of breach is a key consideration for measuring permissible response, and ‘specific and limited’ breach minimises this factor. Purpose: minimise available measures in response.
