If a document refers to a detail in another document, this detail may not be part of the document in a later revision. While referencing documents is easy and stable within a wiki, referencing sections is not. Change the title of a page will change the links to it. Changing the name of a section will not be reflected in the links pointing to it.

Documents should reference related documents that are likely to be changed when the document itself is changed. Documents that relate closely should also have a logical and maybe physical proximity. This makes it easier for readers and authors to find related information.
