Yderligere »kvalifikationsoplysninger« defineret i forbindelse med nationale overvågnings-/akkrediteringssystemer for CSP'er, der ikke udsteder QC'er, kan i det omfang, det er relevant og påkrævet, angives ved tjenesteniveau (f.eks. for at skelne mellem flere kvalitets-/sikkerhedsniveauer ved at anvende »additionalServiceInformation Extension« (punkt 5.5.9.4) som led i »Service information extensions« (punkt 5.5.9).
Additional ‘qualification’ information defined at the level of national supervision/accreditation systems for CSPs not issuing QCs may be provided at the service level when applicable and required (e.g. to distinguish between several quality/security levels) through the use of ‘additionalServiceInformation Extension’ (clause 5.5.9.4) as part of ‘Service information extensions’ (clause 5.5.9).
