mediawiki sub-pages question

Hi all,

I'm having some trouble viewing all sub-pages of a parent, and am tossing
it out to the list for ideas.

Example: The dom <http://docs.webplatform.org/wiki/dom> top-level listing
page contains this line of code:

{{Special:PrefixIndex/dom/}}

which presumably causes it to list everything under it, but the listing
table only goes as far as "dom/HTMLElement/form", which is by no means the
last dom-related page. At the bottom of the page, after the table ends,
there is no "further results" or similar link with which to view more
sub-pages.

The parent page should either list all the pages in one go or paginate them
and provide a "more" link, yes? This help
page<http://www.mediawiki.org/wiki/Help:Subpages> suggests
using the {{FULLPAGENAME}} magic word in place of the literal page name (in
this case, dom/); I tried that, but got the same result.

I don't know how to get the parent to display the rest of the sub-pages.
Any info appreciated.

Thanks,
Dave Gash
