You cannot define a structure without it implicitly acknowledging what functionality archetype will be associated with it. For example, even in a most basic wireframe of a web app if a wireframe showed a left column about 20% wide and 100% height anyone with any experience in software will instantly assume a hierarchical menu of some design. I would agree they aren't tightly coupled but there is definitely an association there that can't be completely separated.
