5.1, Paragraph 3, Sentence 4: Use of "should"; Preciseness in wording

[ERyan71258]

The sentence states: To preserve intended security, full KDM information access should only take place within a secure environment (e.g., within a D-Cinema Secure Processing Block).

For preciseness, move "only" as follows: To preserve intended security, full KDM information access should take place only within a secure environment (e.g., within a D-Cinema Secure Processing Block).

Also: Replace "should". Clause 5 is informative; therefore, "should" cannot be used.

Or perhaps it should be placed in a normative clause.

[palemieux]

Or perhaps it should be placed in a normative clause.

Overall, we should avoid informative clauses (which are not permitted by ISO) -- ofc other than annexes and those clauses that are by design informative, e.g., introduction.
