Article pagination as seen in blog and list layouts is generated in /libraries/joomla/pagination/pagination.php from where it can be overridden within the template.

Intra-article pagination is not included in this file though, so it is not possible to override article>article navigation as would be expected.

Not only is there an issue with it being impossible to override this output from within a template, it also creates a situation where category>article navigation and article>article navigation have a different appearance. Although such UI differences may appear unimportant they can be extremely damaging to UX (User: "is this article navigation? It doesn't look like the article navigation on the last page...").

I beleive that these elements should share a common set of markup, as they are preforming an identical function, and for the users benefit they should look the same.

If I knew where, or how, to go about fixing this (by including the article pagination within pagination.php) I would. I don't, so apologies in advance on that count.
