There were multiple cases where a single standard actually covered several concepts. For example:
(69) ``The competent electoral authorities shall publish an official list of the software used in an e-election or e-referendum. Member states may exclude from this list data protection software for security reasons. At the very least it shall indicate the software used, the versions, its date of installation and a brief description. A procedure shall be established for regularly installing updated versions and corrections of the relevant protection software. It shall be possible to check the state of protection of the voting equipment at any time.''
Its length alone is an indication that it covers more than one concept. Such standards were broken up for consideration in the restructuring process, and sub-standards referred to using letters. (69) was split into (69a) (``The competent ...description.'') and (69b) (``A procedure ...any time''). In many cases, these sub-standards were then merged with other standards, rephrased, contradicted or left out. See below.
