My thoughts on this are more of a reflection on possible futures for quality systems.
There are many ways to present a quality management system to a user, and when thinking about how you want to manage, control and label the information within it, you should think about how you expect your users to find and access it.
For example, a company that have paper copy manuals in every office might think about numbering the sections and pages and providing a paper index at the front. A company that uses and entirely web based system where information is presented on any number of interlinking web pages might use the web address to label the document/information and provide search functions in different ways to access the information.
Whatever it is, as many others have already said here, it should be designed to work for you and your business.
