[Mediawiki-l] Newbie <rss></rss> question

[John Bidder]

Hi

I've seen a number of Wiki's where <rss> </rss> enables the url pointing
directly to an rss feed to display in a main article.  There's been no
javascript going on, no apparent extras in the code at all.

Some Wiki versions have been more recent and some older than mine.
When I attempt this with my Wiki (v1.5.6)  the url renders literally as the
URL - ie. <rss>webaddress</rss> .

Any suggestions in simplest terms appreciated,

Thanks

John
