That PDF/A URL surprised me. Curiously, Wikipedia doesn't think it's a page or a subpage. https://en.wikipedia.org/wiki/Special:PrefixIndex/Wikipedia:PDF http

  I think the reason it's not appearing there is because you're looking in the "Wikipedia:" namespace, which is actually used for meta pages, not articles (e.g: https://en.wikipedia.org/wiki/Wikipedia:FAQ https://en.wikipedia.org/wiki/Wikipedia:FAQ). Searching under the Article namespace (which contains the actual contents of the encyclopedia), it is included: https://en.wikipedia.org/wiki/Special:PrefixIndex/PDF https://en.wikipedia.org/wiki/Special:PrefixIndex/PDF

  Wikipedia has subpages disabled in the main article namespace, which makes slashes in article names possible. https://en.wikipedia.org/wiki/WP:TITLESLASH https://en.wikipedia.org/wiki/WP:TITLESLASH
