That was intended to be an example under the current definition. It might help to put it together, the definition would be the current set of web pages [1]:

“collection of Web pages that share a common purpose and that are created by the same author, group or organization”.



With Matt’s example (as many of the definitions have examples):

“Example: A publication is split across multiple Web pages, where each page contains one chapter or other significant section of the work. The publication is logically a single contiguous unit, and contains navigation features that enable access to the full set of pages.”



Another thing ‘set of web pages’ could describe is a “progressive web application” [2] aimed at mobile devices, e.g:

“Example: A web application intended to be accessed from one initial URL but with multiple pages or views available offline after the initial load of that URL.”

[Jason] I have problems with this approach of trying to sneak in what are arguably normative changes by leaving the definitions untouched and adding examples to address use cases that the definitions (again, arguably) don’t cover. In other words, this solution tries to exploit ambiguities in the definition of “Web page” without actually changing it to remove those ambiguities.



Instead, what I think is necessary is a rewrite of either or both definitions.
