I just saw you are mentioning ETSI 102 042 and ETSI 101 456, both 
standards are now "historical" and therefore not longer valid auditing 
standards. ETSI regrouped auditing standards under 319 401 and 319 411. 
Please consider this when re-writing the membership application form.

Thanks, Benedikt
