Can you give an example of software supporting this?

Brion,

here you are: http://www.mediawiki.org/wiki/Bugzilla/4198

a concise page

Created attachment 3064
Sample patch (does not quite work)

It's fairly easy to stick the fragment onto the media URL as in attached patch,
but it doesn't actually work for the requested use.

Fragment identifiers on wiki links are normalized at link resolution time to
match section id headers; this turns the "=" into '.3D".

Not sure if there's a good way around that other than ripping in and redoing
how fragments are dealt with so it can be normalized differently for certain
types of output link.

To show a page of a pdf, you can use [[File:PDF.pdf|page=n]], maybe it is the best, to also use page= for [[Media:PDF.pdf|page=n]] to link to a page of the pdf.

Is the #Page=3 syntax part of any specification? I suspect it is an feature of some PDF plugins. It doesnt work on OSX Firefox+Preview. It does work in Safari+Adobe plugin.

This has been raised as bug 14788, for djvu files but the same problem exists for any multi-page file format.

Mostly adobe software... http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf#page=7

other formats (movies maybe) I think also use fragments for similar purposes (not sure)

Was that meant as a suggestion for implementation, or what else? It does not work for me.

[[File:PDF.pdf|page=n]] should work at the moment to include a page of a multi page file into the wikipage

[[Media:PDF.pdf|page=n]] is a suggestion for implementation for a link to the page of the multi page file, with the #page= anchor.

I can't find how to add related links in the bug header, so here is a link to the closely related bug: T16788 (formerly bug 14788)
