The precise scope of application of Volume 6 is specified in the Scope of Application Chapter contained in each Module (except those listed in the 'Introduction' part of Volume 6): these specify the particular activities (and associated persons) to which the requirements in the Module concerned apply. In addition, each Rule (or Section containing a series of Rules) is drafted such that its application is clearly highlighted for the user. Finally, each Module, in its Purpose Section, specifies in all cases the rulemaking instrument(s) used to issue the content of the Module in question, and the legal basis underpinning the Module's requirements.
