I wonder if it is possible to have Mediawiki style headings linking to sections within an article, like:-

=heading=
==section1==
==section2==
etc.

I hope this makes sense and apologise if it has been asked before but I did not find it.
I think it would help in incorporating an existing Wikipedia article, say, but also allows for an elegant and simple way to lay out the page.
Thank you.
